Personal Update on the Malibu Fires
An update to our earlier post about evacuating our home because of the Malibu brush fires. Rest assured we are okay. Got back into our home this past Tuesday. Still no power, but water (and toilet) is working. Local hotel hosted all evacuees for Thanksgiving dinner. God bless all our fires fighters, first responders and volunteers.
Our home is okay, just a few singed palm trees and spots of burnt brush. Thanks to God.
A few photos for you. Continue to pray and send us your positive thoughts. Will write more soon.
A-Fib Self-Care Skills: How to Check Your Heartbeat and Heart Rate
Some Atrial Fibrillation patients know immediately when their heart is in A-Fib. They experience one or more symptoms including shortness of breath, palpitations, heart flutters, etc. Other A-Fib patients may have subtle symptoms (or silent A-Fib) and can’t be sure.
The following self-care skills will reassure you any time you suspect you’re in A-Fib—how to check for an irregular heartbeat and how to tell if your heart rate is too fast or too slow.
Self-Check if Your Heartbeat is Regular or Irregular
I found an informative post with these self-care skill steps on the Scope Blog by Stanford University School of Medicine. To check whether your heartbeat is regular or irregular:
♥ Begin by placing your right hand on the left side of your chest while seated and leaning forward.
♥ Position your hand so that you feel your heartbeat most strongly with your fingertips.
♥ A normal heart rhythm should feel like a regular drum beat cadence; you can usually anticipate when each beat will come after the last beat.
♥ Because heart rate and the strength of the heartbeat can vary with breathing, sometimes holding your breath for a few seconds is helpful. With an irregular rhythm, it will be hard to predict when the next beat will come.
♥ In addition, some irregular beats will be softer (less strong) than other beats, so the strength as well as the timing may not be consistent.
Self-Check If Your Heart Rate is Too Fast or Too Slow
The Stanford blog continues with a second set of self-care skill steps—how to measure if your heart rate is too fast or too slow so you know when to seek medical care. (An optimal heart rate is 50–100 bpm when you are at rest.) To check your heart rate:
♥ Place your right hand over your heart so that you feel your heart beating under your fingertips.
♥ Use a watch or timer and count the number of beats for 15 seconds.
♥ Be sure to count all heartbeats; including beats that are not as strong or that come quickly following one another.
♥ Take the number of beats you’ve counted and multiply it by four. For example, if you count 30 beats in 15 seconds, then you would calculate 4 x 30 = 120 beats per minute.
♥ Repeat this process three times right away, writing down each heart rate to later share with your doctor.
While an Electrocardiograph (ECG or EKG) or Holter monitor are the only sure ways to document you are in A-Fib, you can use the above self-care skills to recognize A-Fib symptoms of an irregular heart beat or if beating too fast or too slow.
These skills with help you remain calm and confident when you suspect you may be in A-Fib.
Part II Framingham Study: Research Milestones in Heart Disease and Atrial Fibrillation
Now celebrating its 70th year, the Framingham Heart Study (FHS) is a long-term, ongoing cardiovascular study of residents of the city of Framingham, MA, a small, middle-class community 23 miles west of Boston.
Starting in 1948, the objective of the Framingham Heart Study was to identify the common factors that contribute to cardiovascular disease by following its development over a long period of time. Participants would have no overt symptoms of heart disease and not suffered a heart attack or stroke. Today 15,447 people of varying ages, backgrounds and heritage are enrolled including second and third generations.
Findings Integral to Scientific Understanding A-Fib
The Framingham study has contributed greatly to our understanding of Atrial Fibrillation and to the risk of stroke, heart attack and heart failure. A few important milestones about A-Fib include:
1957 High blood pressure and high cholesterol levels increase likelihood of heart disease
1960 Cigarette smoking found to increase the risk of heart disease
1970 Atrial fibrillation increases stroke risk 5-fold
1982 Chronic atrial fibrillation associated with a doubling of overall mortality and of mortality from cardiovascular disease
1991 Atrial fibrillation as an independent risk factor for stroke
1994 Diabetes and hypertension risk factors for atrial fibrillation
2002 Obesity is a risk factor for heart failure
2009 New genetic variant associated with increased risk for atrial fibrillation
2010 Sleep apnea tied to increased risk of stroke
2010 Having first-degree relative with atrial fibrillation associated with increased risk
Framingham Research: Expect More Findings About Atrial Fibrillation
Framingham scientists circa 1948
Framingham data resources are available for researchers to use, and those data continue to spur new scientific discoveries. The study data has spawned over 3,600 published studies in medical, peer-reviewed journals.
As A-Fib patients, we owe a huge debt to the Framingham participants, doctors, scientists and researchers. With continuation of the Framingham Heart Study, we can expect more research findings about Atrial Fibrillation for years to come.
Celebrating 70 Years of the Framingham Heart Study: Solving Mysteries of Heart Disease
When I first started researching my A-Fib back in 1998, I kept coming across research studies that credited its data to the Framingham Heart Study. I had no idea how influential the study has been to expanding our understanding of cardiovascular health.
The Framingham Heart Study (FHS) is a long-term, ongoing cardiovascular study of residents of the city of Framingham, MA, now celebrating its 70th year. The study was commissioned by the U.S. Congress and had been intended to last for only 20 years.
The Lifesaving Power of Scientific Research
Much of the now-common knowledge concerning heart disease, such as the effects of diet, exercise, smoking, good and bad cholesterol and high blood pressure is based on this longitudinal study. As well as far-reaching programs in stroke and Alzheimer’s.
Before the FHS, doctors had little sense of prevention.
“It’s no coincidence that deaths from heart disease have declined over the 70 years of this groundbreaking study.”
–Nancy Brown, CEO, AHA
American Heart Association CEO Nancy Brown said new approaches and therapies have sprung from Framingham’s work. “Framingham is living proof of the lifesaving power of scientific research. It’s no coincidence that deaths from heart disease have declined over the 70 years of this groundbreaking study.”
The study has huge repositories of data, from cell lines and gene sequences to scanned images of the heart, brain, bone and liver.
“Every part of the body that can be measured, imaged or assessed, we’ve done so over the last 70 years,” said Dr. Vasan S. Ramachandran, principal investigator and director of the study for Boston University. “It’s a remarkable human experiment. It’s with humility I say that. It’s unbelievable, and to be part of it is a gift, a privilege and an honor.”
Framingham: The Study and the Town that Changed the Health of a Generation
Framingham doctors in 1948
The study began in 1948 with 5,209 adult subjects (mostly white women and men) from Framingham, (about two-thirds of the town) and now has over 14,000 people from three generations.
Participants, and their children and grandchildren, voluntarily consented to undergo a detailed medical history, physical examination, and medical tests every two years, creating a wealth of data about physical and mental health, especially about cardiovascular disease.
Judie Saltonstall is one of them. She’s a second-generation participant who moved to Arizona 29 years ago and still faithfully logs on to her computer every three months to answer questionnaires and memory quizzes.
FHS participants live all over the country and travel back to Framingham whenever needed for exams and tests.
The 75-year-old is part of a contingent of FHS participants living all over the country who travel back to Framingham whenever needed for exams and tests. She reels off a list: retina photographs, bone density tests, and MRIs of the brain, heart and abdomen.
“It’s kind of exciting to do,” said Saltonstall, a mother of four and a former teacher. “It’s important for me personally, but also for them to know what’s going on with me and to learn from that, whatever good it does.”
Adding Different Segments (“Cohorts”)
In 1968, despite the recommendation to end the study as scheduled, Congress voted to continue it. Over the decades, the study had been split into different segments, or “cohorts”:
To study race and heritage in heart factors, The Omni Cohort (1994) asked people of color to volunteer; The Omni Two Cohort (2003) is the 2nd generation.
• The Original Cohort (1948)
• Offspring Cohort, the second generation (1971)
• The Omni Cohort asked people of color to volunteer to study race and heritage in heart factors (1994)
• The Generation Three Cohort (2002)
• The Omni Two Cohort, the second generation of Omni Cohort participants (as young as 13 years of age, 2003).
Landmark Study: Inspiring Thousands of Published Studies
Framingham, MA, circa 1948
It’s been 70 years since a small, middle-class community 23 miles west of Boston became the linchpin in helping to solve the mysteries of heart disease.
Framingham data resources are available for researchers to use, and those data continue to spur new scientific discoveries. FHS data has spawned over 3,600 published studies in medical, peer-reviewed journals. (Including many studies about Atrial Fibrillation, heart arrhythmias, and prevention of strokes).
The Framingham Heart Study is a joint project of the U.S. National Heart, Lung, and Blood Institute (NHLBI) and Boston University. Learn more at News on Framingham Heart Study.

Apple Watch 4: Do ECG Readings Give A-Fib Patients a False Sense of Security?
We received a couple of emails about the new Apple Watch 4. As many A-Fib patients may be aware, recently Apple unveiled the next generation of Apple Watch which includes a second generation optical heart sensor.
Among several interesting features, it can generate an ECG tracing similar to that of a single-lead electrocardiograph.
In her Sept. 14, 2018 editorial on Medscape.com, ECG Readings From the Apple Watch? This Doctor Is Leery, Dr. Hansa Bhargava gives her perspective of this feature for those diagnosed with atrial fibrillation. She writes that she finds the Apple Watch’s ability to do a one-lead ECG interesting but has some reservations.
“…Here’s what I worry about: the false sense of security that a person could have.
Apple Watch 4 screens
Being able to do a one-lead ECG is definitely interesting, but does it always help? Here’s a scenario. A 40-year-old runner starts feeling dizzy, lightheaded, and has chest pain. He worries but remembers that there is an ECG function on his watch. He proceeds to do the ECG which then reads “normal.” Because of this he decides to continue to run.
What he doesn’t know is that this is only a one-lead ECG, and even though it seems normal, it is an isolated data point; more information is needed to diagnose what is going on. What if he is having angina? In fact, 30% of cardiovascular events happen to people under the age of 65. One lead on an ECG could certainly miss this; in fact, even a 12-lead ECG, if the only isolated data point, could miss this.
Dr. Andrew Moore, an emergency department physician at the Oregon Health and Science University is also skeptical of the Apple Watch 4 ECG feature:
“The ECG thing is a little bit overhyped in terms of what it will really provide. …The tech that Apple is working with is very rudimentary compared to what we’d do for someone in a hospital or health care setting.”
While the watch can detect changes in the patterns of a person’s heart rate such as too fast, too slow, or beating irregularly—signifying A-Fib, the watch doesn’t diagnose a medical issue.
Apple Watch and Other DIY Heart Rate Monitors
Guide to HRMs and Handheld ECG monitors
Keep in mind these doctors’ concerns apply to all consumer heart rate monitors (HRM), those with optical heart sensors and those with electrode-containing monitors.
Wrist vs. Chest Bands: Wrist-band optical heart-rate monitors (like Apple Watch 4) may be more convenient or comfortable and have advanced over the years. But researchers found that electrode-containing chest-strap monitors were always more accurate than their wrist counterparts and more reliable and consistent. To learn about this research, read When Tracking Your Heart: Is a Wrist-Worn Heart Rate Monitor Just as Good as a Chest Strap Monitor?
Blue-tooth chest-band with smartphone app
As an A-Fib patient, when monitoring your heart beat rate is important to you (while exercising or doing heavy work), you’ll want to stick with an electrode-containing monitor (chest band-style, shirts or sports bras with built-in electrode pads, etc.).
For help selecting a HRM, see our article: Guide to DIY Heart Rate Monitors (HRMs) & Handheld ECG Monitors (Part I). Also take a look at Steve’s list on Amazon.com: Top Picks: DIY Heart Rate Monitors for A-Fib Patients.
Keep in mind: None of these DIY heart rate monitors are diagnostic tools. But they can be helpful once you know you have A-Fib, A-Flutter or suffer from PVCs, PACs, etc. Just don’t make medical decisions based on their readings. See your doctor if you have any concerns or symptoms.
Remember: None of these DIY heart rate monitors are diagnostic tools
September is A-Fib Awareness Month: The Threat of ‘Silent A-Fib’
‘That Demon A-FIB ZEBUB’
During September each year, we focus our efforts on reaching those who may have Atrial Fibrillation and don’t know it. ‘Silent A-Fib’ is a serious public health problem. In his personal A-Fib story, Kevin Sullivan, age 46, wrote about his diagnosis of Silent A-Fib.
“I was healthy, played basketball three times per week, and lifted weights. I started to notice on some days playing basketball, I was having some strange sensations in my chest. And sometimes, difficultly catching my breath. But the next day I would feel fine. I assumed this was just what it felt like to get old.”
At the time, he happened to see a cardiologist about medication for high cholesterol:
“I went to see a cardiologist. They looked at my heart with ultrasound and asked if I could feel “that.” I asked them what they were talking about, and they told me that I was having atrial fibrillation. That was the first time I had ever heard of the phrase.”
Like Kevin Sullivan, about 30%–50% of people with Atrial Fibrillation are walking around not knowing they have it. They may get used to their symptoms or they write off the tiredness, dizziness or mental slowness to growing older, but their heart health may be deteriorating.
Untreated, about 35% will suffer a stroke (half of all A-Fib-related strokes are major and disabling).

Review: CONTEC Handheld Portable ECG Heart Rate Monitor (PM10)
Tim Zhang from Contec Medical Systems CO., LTD, offered us a Contec Handheld Portable ECG Heart Rate Monitor, PM10, to try for ourselves hoping we would add it to our reviews of other similar units.
Contec PM10/EMAY Ltd EMG-10
The Contec PM10, an FDA Certified device, is also sold as the EMAY Ltd EMG-10. Both handheld portable ECG heart rate monitors are about $79 on Amazon.com. The PM10 is a small 4 oz. unit that can track a single channel ECG waveform. You can observe the scan live, then download the recordings (up to 30) to your computer or smartphone for review and print to share with your doctor. It claims to detect up to 12 cardiac conditions. I don’t have A-Fib anymore (thank goodness), so I wasn’t able to test while in A-Fib.
The user guide’s small size, tiny printing and wording leaves a lot to be desired. (Note: You can find the guide on the internet and download in a normal full-size page layout.)
Easy to Record an ECG, But Requires Software to Review
To charge the PM10 battery: Use the provided micro USB cable to connect the unit to a USB port on your computer. While charging, you’ll see a faint blinking blue light beneath the white plastic at right top front of the curved end.
Taking a scan (no cable or smartphone needed): To turn on, press the blue button (the only button on the unit) and hold down for 3-4 seconds and you’ll hear a beep (it turns off automatically). You’ll notice the metal contacts are sizeable on this relatively small device.
Measurement positions of Contec PM10
Hold the unit as shown in the drawings (between both hands, or hold with one hand and the unit on your chest.) You can watch the unit capture your heart beats. It takes a few seconds for the waveform to stabilize, then start recording for a 10 sec measurement. (There’s a 10 sec countdown on the screen). It displays your heart rate as well.
Summary screen: When completed, the ECG scan is replaced with a summary screen with its best guess about the recording. Examples: No abnormal, Bradycardia, Missed beat. You can’t review the recording on the unit. You must download to software on your computer or smartphone.
Contec PHMS App or Software
The PM10 connects by Bluetooth or USB cable to a smartphone phone or computer. You’ll want to install the app or software so you can download your scans for review or printing. The PHMS app can be found on iTunes and Google Play.
Download screen opens first
For a computer, you can download the PHMS software from the Contecmed.com download page or the EMAY Ltd download page (I found EMAY easier and faster).
Reviewing your recordings: On my laptop I connected to the PM10 just like when I charged the battery. (The first time you might want to open the software, then connect the cable and the PM10.)
Manage tab with downloaded scans
The ‘Download’ tab opens first. Press the ‘Start new search’ and the software displays a list of scans from your PM10. Press the button ‘Download all’. Then switch to the ‘Manage’ tab. From here you can select a scan from the list and press ‘Review’ to see the ECG. A Diagnosis column is on the right.
Review screen with ECG and data
From here you can print the scan. (To close, double-click on the ECG to return to the downloaded list).
Helpful tip: When you ‘print’ you can also select ‘Adobe PDF’ as your printer and save to your hard drive, but I had poor image results. An alternative is to take a screenshot or use the Windows snipping tool. Save the image, then print. Either way, you can attach it to an email and send to your doctor.
Amazon.com Contec Reviews from Customers with A-Fib
A curious point about the Amazon.com reviews: The Contec PM-10 has a customer review rating of 3.1 out of 5 stars, whereas the EMAY EMG-10 has a customer rating of 4.5 out of 5 stars. From scanning the reviews, EMAY purchasers are happier with their contacts with EMAY customer service. (I’ll let you draw your own conclusions.)
Use the A-Fib.com portal link to Amazon.com
I’ve included comments from three reviewers (who mention having A-Fib) on the Contec PM10 product page:
• A Contec review on Amazon.com by Ron Crist noted there’s no hidden fees like other popular devices (e.g. monthly fee for Kardia Heart Monitor by AliveCor). He went on to write: “I have persistent AFib and have had 2 crippling strokes. No more cardioversions (electric shocks) for me. I hope. I Strongly recommend it.”
• A doctor with A-Fib, PD, wrote on Amazon.com: “This is a very good machine but ekg has some static. I am a doc with atrial fib and this helps in terms of heart rate and ekg…took some experimenting [to set up] but the results are gratifying…Once set up I give it 5 stars.”
• An Amazon reviewer with paroxysmal atrial fibrillation writes: “This monitor allows me to see just when my condition occurs and gives my cardiologist a better picture of my condition. Although not a perfect answer it does enhance the overall picture.”
You can read the Amazon.com reader reviews for yourself at the Contec PM10 and the EMAY EMG-10 product description pages.
Lightweight, Easy to Use, But Not a “Diagnostic” Device
Contec PM10 box & contents
The Contec PM10 is easy to use and carry in a pocket or handbag for scans on the go. Or leave with your laptop for periodic checks. While you can observe the ECG scan live on the screen, there’s no review screen. You must download the scan to review it or print it.
Unlike the AliveCor Kardia, no smartphone or tablet is needed to take scans. Observing the live ECG tracing may be enough for most A-Fib patients who just want a quick check of their heart beat and heart rate. I think you get a lot for the $79 price.
But remember this is not a diagnostic device. It doesn’t replace an ECG by your doctor or use of a mobile type of heart rhythm monitor to capture the electrical activity of your heart (e.g., a Holter monitor or event monitor).
I welcome your comments if you have used this unit or others in our reviews, Guide to DIY Heart Rate Monitors (HRMs) & Handheld ECG Monitors (Part I) and Do-It-Yourself ECG: A Review of Consumer Handheld ECG Monitors. Just send me an email.
Vitamin K―Protection Against Arterial Calcification & Cardiovascular Disease
Most people get just enough Vitamin K from their diets to maintain adequate blood clotting.
But NOT enough Vitamin K to offer protection against health problems including arterial calcification, cardiovascular disease, osteoporosis, various cancers and brain health problems, including dementia.
The name Vitamin K comes from the German word “Koagulationsvitamin” where its role in blood coagulation was first discovered.
Vitamin K is an essential vitamin. It is one of the four fat-soluble vitamins, along with vitamin A, vitamin D, and vitamin E. It’s found in leafy green vegetables, broccoli, and Brussels sprouts.
Vitamin K and Vitamin K supplements come in several forms and can be confusing. To increase your levels of Vitamin K, it’s important to understand the differences.
Vitamin K Can be Classified as Either K1 or K2
Vitamin K1: Found in green vegetables, K1 goes directly to your liver and helps you maintain a healthy blood clotting system; keeps your own blood vessels from calcifying, and helps your bones retain calcium.
Vitamin K2: Bacteria produce this type of Vitamin K; it goes straight to vessel walls, bones and tissues other than your liver. It is present in fermented foods, particularly cheese and the Japanese food natto (the richest source of K2).
Different Forms of Vitamin K2
Making matters even more complex, there are several different forms of Vitamin K2. MK-4 and MK-7 are the two most significant forms of K2 and act very differently in your body.
MK-4 is a synthetic product, very similar to Vitamin K1, and your body is capable of converting K1 into MK4. It has a very short biological half-life of about one hour, making it a poor candidate as a dietary supplement. It remains mostly in your liver where it is useful in synthesizing blood-clotting factors.
MK-7 is a newer agent with more practical applications because it stays in your body longer; its half-life is three days, meaning you have a much better chance of building up a consistent blood level, compared to MK-4 or K1. It slows down cardiovascular aging and osteoporosis, and prevents inflammation by inhibiting pro-inflammatory markers produced by white blood cells.
Food Sources of Vitamin K and MK-7
Photo by Like_The_Grand_Canyon on Flickr licensed CC-BY
MK-7 is extracted from the Japanese fermented soy product called ‘natto’. You get loads of MK-7 from natto. However, natto is generally not appealing to a Westerner’s palate (can’t tolerate its smell and slimy texture).
You can also find Vitamin K2, including MK-7, in other fermented foods including some fermented vegetables.
Certain types of fermented cheeses (Jarlsberg) are high in K2 but others are not. It really depends on the specific bacteria. You can’t assume that any fermented food will be high in K2.
Besides broccoli, Brussels sprouts and leafy green vegetables (kale, mustard greens, collard greens, raw Swiss chard, spinach), other foods high in Vitamin K include beef liver, pork chops and chicken, prunes and Kiwi fruit, soybean and canola oil.
Vitamin K Supplements
Choosing a K2 supplement: When supplementing your Vitamin K food sources, consider a high quality MK-7 form of vitamin K2. (Plus, as they are inexpensive, include Vitamin K1 and MK-4 to help inhibit and possibly reverse vascular calcification.)
Relentless Improvement
Dosage: Although the exact dosage of Vitamin K is yet to be determined, one of the world’s top Vitamin K researchers, Dr. Cees Vermeer recommends between 45 mcg and 185 mcg daily for normally healthy adults.
My choice: I’m taking Relentless Improvement Vitamin K2 MK4 Plus MK7; Read about it on Amazon.com. David Holzman writes that he uses Whole Foods Vitamin K2 which is less expensive. (Use our portal link to Amazon.com and support A-Fib.com)
(If you have a K2 supplement recommendation, email me.)
Remember!
Always take your Vitamin K supplement with food that contains fat
since it is fat-soluble and won’t be absorbed without it.

Medicines, Herbs and Supplements: ‘Natural’ Doesn’t Necessarily Mean Safer, or Better
By Patti Ryan, based on an article from the National Institutes of Health
Nature has been good to us. Nature gave us aspirin and morphine, and other medicines derived from plants. The use of plants as medicines has a long history in the treatment of disease, and plants have played an important role in improving our health.
“Natural” vs. “Unnatural”
A lot of people believe that when it comes to medicine, “natural” is better, healthier and safer than “unnatural” or synthetic drugs.
Medicine and supplements: Is “natural” better, healthier and safer?
On the other hand, not all products from nature have been shown to be effective. Some dietary and herbal supplements have failed to show a benefit when scientists have studied them.
For example, several major studies of the herb Echinacea did not find evidence of benefit against the common cold. Studies of ginkgo, including a large study that enrolled more than 3,000 older adults, found that ginkgo supplements don’t help prevent or slow dementia or cognitive decline.
“Natural” Medicines Can Have Side Effects Too
Contrary to what many may think, some “natural” medicines can even have serious safety concerns.
For example, kava, a plant native to the islands of the South Pacific, and often used as a dietary supplement for anxiety, may be associated with severe liver damage.
Ephedra, an evergreen shrub-like plant native to central Asia and Mongolia that has been used for centuries for colds, fever, and other conditions, is associated with heart problems and risk of death. (In fact, the U.S. FDA banned dietary supplements with ephedrine alkaloids.)
Free of chemicals? ... But everything is made of chemicals!
Are “Natural” Medicines Chemical Free?
Some people also believe that “natural” products are safe because they believe these medicines are free of chemicals. For many, the word “chemical” has come to mean toxic or synthetic, something to be avoided.
But everything is made of chemicals. The apple on your kitchen countertop, the ceramic mug in your cupboard, and even the air that you breathe. In fact, you are made up of chemicals, too.
Some chemicals in nature are toxic to us—mercury, snake venom, arsenic, and ricin from castor beans. But other chemicals are good for us and necessary for life—like iron and oxygen (but at high doses are toxic and can even cause death).
When Considering a Herbal or Dietary Supplement
Do your research first!
It’s important to understand that although many herbal or dietary supplements (and some prescription drugs) come from natural sources, “natural” does not always mean that it’s a safer or better option for your health.
And a “chemical” ingredient can be beneficial. An herbal supplement may contain dozens of chemical compounds (but all of its ingredients may not yet be known).
Before you add herbals and supplements to complement your treatment plan, do your research! Strive to make informed decisions about your health.
Our Favorite Resources on Vitamins, Herbs and Supplements
Take charge of your health by being an informed consumer. Find out what the scientific evidence says about the safety of a supplement and whether it works. A good place to start is an unbiased, non-commercial searchable database. Here are our favorites:
1. Memorial Sloan Kettering Cancer Institute/Integrative Medicine: “About Herbs, Botanicals & Other Products”
2. Drugs.com: ‘MedFacts Natural Products Professional database’
3. The ‘Dietary Supplement Label Database’ and Herbs at a Glance at the U.S. National Institutes of Health.
For a detailed report, see our FAQ: Where can I find reliable, unbiased research and information on specific vitamins and supplements?
Don’t Forget: Keep Your Health Care Providers Informed
To use vitamins, herbs and supplements safely, read and follow the label instructions, and recognize that “natural” does not always mean “safe.”
It’s important to tell all your health care providers about all supplements you take. Be sure to update this information every time you visit your doctors’ offices. That way, they can help you avoid harmful interactions.

The trap for those who work hard at improving nutrition and supplements is they feel like a failure if they can’t stop their A-Fib with natural means alone. They keep trying one thing after another for years while avoiding an expert’s opinion about an ablation procedure.
Of all the 90+ personal A-Fib stories we’ve published on A-Fib.com, we only have one who states she was cured by natural supplements. (She takes much more than just magnesium and started when she first developed A-Fib.)
But trying natural remedies for A-Fib shouldn’t be an ‘either/or’ decision.
We should use every tool possible to put the ‘A-Fib genie back in the bottle’.
We should use every tool possible to put the ‘A-Fib genie back in the bottle’. The best approach is to combine an expert ablation procedure with permanent dietary improvements (including heart healthy nutrients and supplements) while also addressing any appropriate life-style changes (i.e., for high-blood pressure, sleep apnea, diabetes and obesity).
For someone who has just developed A-Fib, try to get out of A-Fib ASAP. It goes without saying that it’s not healthy and feels terrible to have A-Fib attacks.

Reminder About “Holiday Heart”: Binging Alcohol, Marijuana or Rich Foods
Be aware! It’s the time of year when many people end up in a hospital’s emergency room (ER) for treatment of “Holiday Heart Syndrome”, i.e., Atrial Fibrillation triggered by binging—on alcohol, heavy foods and recreational marijuana.
Overindulging in alcohol (six or more drinks) can cause surges in the body’s adrenalin, rises in the levels of free fatty acids, alterations of how sodium moves in and out of the heart cells, and a lowering of the levels of sodium, potassium, and magnesium in the body through diuresis (increased or excessive production of urine).
Does Alcohol Alone Explain Holiday Heart Syndrome?
Trigger: marijuana use
Excessive alcohol is not the only culprit. Recreational use of marijuana can compound the risk as well. Other factors include the nicotine effect in smokers (active and passive), large quantities of rich food, and even cold weather. In addition, fireplace fires and bonfires can release ultra-fine particles in the air from burnt materials and can be bad for the heart.
New Year’s Eve Party Time: Be Aware
As you celebrate, encourage others to avoid heavy alcohol consumption and try to minimize eating large quantities of food at one time. Look for the symptoms of “holiday heart” among your relatives (hereditary A-Fib) and friends. Anyone with any heart symptoms should go to the ER. If they’re lucky, it will be a one time event.
Share the Cheer of the Season
Finally, if you know someone who is depressed, alone, or isolated during the holiday season, reach out and cheer them up.
It may be the best thing you do for their heart as well as yours.
Chocolate and Reduced Risk of Atrial Fibrillation: A 13-Year Study
In 2017, there’s more on the health benefits of chocolate! Accumulating evidence links chocolate to heart health and now, a lower risk of atrial fibrillation.
A 13-year Danish study published in 2017 tracked the health of 55,000 participants, aged 50–64 years. During the period, more than 3,300 cases of atrial fibrillation emerged. All of the participants had completed detailed questionnaires about their lifestyles, everything from exercise habits to what they ate and drank, including how much chocolate they consumed.
Study Results: Chocoholics Delight
“Our study adds to the accumulating evidence on the health benefits of moderate chocolate intake,” said lead author of the study Elizabeth Mostofsky of Harvard School of Public Health.
Compared to those who ate a 1-ounce serving of chocolate less often than once a month, the risk of atrial fibrillation was:
• 10 percent lower among those who ate one to three servings a month
• 17 percent lower among those who ate one serving a week
• 20 percent lower among those who ate two to six servings of chocolate a week
Benefits of All Types of Chocolate
Dr. LeWine added that while scientists aren’t sure why chocolate seems to boost heart health, it may be related to flavonoids, a type of antioxidant produced by plants.
Flavonoids are particularly abundant in cacao beans and have been shown to help lower blood pressure, improve blood flow to the brain and heart, prevent blood clots, and fight cell damage. They’ve also been shown to help thinking skills.
To Avoid A-Fib: How Much Chocolate?
The study results found “the rate of atrial fibrillation was 20 percent lower for people consuming two to six 1-ounce servings [of chocolate] per week”.
While no recommended daily amounts have been set when it comes to chocolate (or cocoa flavonoids), the European Food Safety Authority suggests that 200 mg of cocoa flavonoids per day is a good target for the general population.
What Patients Need to Know
To reap the various health benefits of chocolate, the higher the cocoa content of the bar, the better. Look for chocolate bars with 70% cocoa or more. You may have to do some detective word, as the amount of cocoa used in chocolate varies a lot (and the amount of flavonoids in chocolate is not always listed.)
Your best bet is to stick with dark chocolate. As a general rule, dark chocolate has more cocoa and therefore more flavonoids than milk chocolate (and less sugar and saturated fat).
To Find Your A-Fib Cure, Build Your ‘Dream Team’
Treating Atrial Fibrillation doesn’t sound like a team sport. But you don’t beat your A-Fib on your own. It takes a team of healthcare professionals and wellness experts to help you seek your A-Fib cure!
While your ‘Dream Team’ will be unique to you, based on your age, symptoms, and other medical conditions, the core members of your Dream Team’ will include:
♥ Your primary care physician: often diagnoses your atrial fibrillation; may prescribe and manage your initial medications (especially for risk of stroke); usually refers you to a cardiologist (hopefully a heart rhythm specialist).
♥ Cardiac Electrophysiologist (EP): a cardiologist who specializes in the electrical functions of your heart; often the leader of your Dream Team! (Read: How to Find the Right Doctor for You.) In addition to your EP, other cardiac professionals may be added to your team including:
▪Cardiac procedure specialist: if you need a catheter ablation, a left atrial appendage occlusion device, i.e. Watchman, AV Node/Pacemaker procedure, pacemaker, etc.
▪Cardiac surgeon: if you need a Maze surgery or Mini-maze surgery
Recruit Beyond Your Team Starters
Don’t stop with just recruiting your star performers. Many of our readers at A-Fib.com have drafted other healthcare practitioners and wellness experts to join their Dream Team. You may benefit from one or more of the following:
♥ Sleep specialist: More than 40% of A-Fib patients also suffer from sleep apnea. Everyone with A-Fib should be tested (Sleep Lab or home study). In fact, your EP may require testing before agreeing to perform a catheter ablation. Learn more about sleep apnea.
♥ Nutritional counselor/Naturopathic physician: Many A-Fib patients have found relief of symptoms through herbal and mineral supplementation (starting with magnesium and potassium). Learn more about a more integrated or natural method of healthcare.
♥ Diet & Exercise specialist: Losing weight through diet and exercise has benefited many A-Fib patients. Some report their A-Fib symptoms have diminished or stopped completely through changes in lifestyle. Read more about a heart-healthy eating plan.
♥ Complementary treatment practitioners:
▪Acupuncture: Many A-Fib patients have reported relief with acupuncture. Research indicates that acupuncture may have an anti-arrhythmic effect in patients with atrial fibrillation. Read about acupuncture research.
▪Yoga: Many A-Fib patients practice yoga and report benefits, specifically, the number of symptomatic A-Fib events were down, heart beat and blood pressure dropped, depression eased and anxiety decreased. Read about A-Fib and yoga.
▪Chiropractor: Several A-Fib.com patients have reported relief with chiropractic treatments. In addition, a few clinical studies have focused on arrhythmia and ‘manipulation’ techniques. Read more.
How to Build Your ‘Dream Team’
Seek inspiration!
Forming your ‘Dream Team’ is an important step toward seeking your A-Fib cure. To build your team, we advise you to use all the resources available to you. Ask for referrals from other A-Fib patients, family and friends, and from your doctors’ nurses, nurse practitioners and physician assistants.
For inspiration, learn how others have dealt with their atrial fibrillation. Just browse our list of over 90 A-Fib Stories of Hope and Encouragement. Read a few stories with similar symptoms to your own, age group, etc.
Also, consider corresponding with one of our A-Fib Support Volunteers. They’ve all been where you are now. They have been helped along the way, and want to help other A-Fib patients.

New Research into Alcohol & A-Fib: How Many Drinks are Too Many?
“While moderate amounts of alcohol appear protective for the ‘plumbing,’ or blood supply to the heart muscle, the benefits of alcohol do not extend to the electrical parts of the heart, or heartbeat.”
Over time, drinking may actually change the electrical signals, triggering irregular heartbeat (arrhythmias).
Risk per Daily Alcohol Drink
A new study found the risk of atrial fibrillation grew by 8 percent for each daily alcoholic drink. The findings were similar for men and women. The authors looked at previous studies that tracked almost 900,000 people over 12 years.
Fibrosis: The study doesn’t establish a direct cause-and-effect relationship. Nevertheless, “cell damage from habitual drinking may lead to small amounts of fibrous tissue within the heart that causes the irregular, quivering heartbeat”, the study authors said.
Post-catheter ablation: The review found that people who continue to drink are more likely to have ongoing irregular heartbeats even after catheter ablation.
Weekly Alcohol Recommendation
Dr. Pater Kistler recommended that those with irregular heartbeat “should probably drink no more than one alcoholic drink per day with two alcohol-free days a week.”
He added they had no randomized data that tells what a ‘safe’ amount is to consume. The study authors called for more research to determine whether avoiding alcohol completely is required for patients who have irregular heartbeats.
(Added 3/25/2019):
New Study Recommends Complete Abstinence If You Have A-Fib
Participants consuming at least 10 standard drinks per week were randomized to abstinence or usual consumption. Abstinence prolonged A-Fib-free survival by 37% and lowered A-Fib burden from 8.2% to 5.6%. Those in the abstinence arm also experienced improved symptom severity, weight loss, and BP control.
Know Your Triggers
Some Atrial Fibrillation patients have sworn off alcohol altogether. Through trial and error, they’ve found that any amount of alcohol contributes to or triggers their A-Fib episodes.
Dr. Kistler’s research is helpful for the balance of A-Fib patients. It offers some research-based guidelines to minimize the impact of alcohol consumption on their A-Fib.
For additional reading, see my article:“Holiday Heart”: Binging Alcohol, Marijuana & Rich Foods.
But once you are A-Fib free as by a catheter ablation, moderate alcohol consumption may not be a problem or induce A-Fib.
