Doctors & patients are saying about 'Beat Your A-Fib'...
"If I had [your book] 10 years ago, it would have saved me 8 years of hell.”
Roy Salmon, Patient, A-Fib Free, Adelaide, Australia
"This book is incredibly complete and easy-to-understand for anybody. I certainly recommend it for patients who want to know more about atrial fibrillation than what they will learn from doctors...."
Pierre Jaïs, M.D. Professor of Cardiology, Haut-Lévêque Hospital, Bordeaux, France
"Dear Steve, I saw a patient this morning with your book [in hand] and highlights throughout. She loves it and finds it very useful to help her in dealing with atrial fibrillation."
Dr. Wilber Su, Cavanaugh Heart Center, Phoenix, AZ
"...masterful. You managed to combine an encyclopedic compilation of information with the simplicity of presentation that enhances the delivery of the information to the reader. This is not an easy thing to do, but you have been very, very successful at it."
Ira David Levin, heart patient, Rome, Italy
"Within the pages of Beat Your A-Fib, Dr. Steve Ryan, PhD, provides a comprehensive guide for persons seeking to find a cure for their Atrial Fibrillation."

The story goes that when Steve Ryan started planning his website for A-Fib patients (A-Fib.com), the top priority was presenting up-to-date medical and research information but in layman’s terms, not medicalese.
That’s where Patti Ryan enters the picture.
With a background in corporate communications, she pledged to fight tooth ‘n nail, if needed, to represent the patients’ point-of-view and drum out as much medical jargon as possible. And, yes, there were many heated “discussions.” Patti also contributes her graphics and photography savvy to both A-Fib.com and and the publishing of the book, Beat Your A-Fib: The Essential Guide to Finding Your Cure (BeatYourA-Fib.com).
Patti has earned a B.F.A. in Fine Art, a B.S. in Communications, and university certificates in business management and corporate training. Her professional experience ranges from graphic design and digital photography to corporate video production, and business management. In the past few years she has focused on creative project design and writing for the craft and home décor magazine/book publication markets.

As part of your education about Atrial Fibrillation, you’re bound to run across terms that you do not understand. Bookmark our Glossary of Medical Termspage (or click on “Glossary of Terms” in the left menu) and refer to it when reading and studying about A-Fib.
Our A-Fib.com Glossary of Medical Terms and Phrases is the most complete online source devoted exclusively to Atrial Fibrillation. Each definition is written in everyday language—a great resource for patients and their families.
A Sampling of Glossary Terms
To give you an idea of what you’ll find, we’ve selected a few Atrial Fibrillation terms and phrases related to drug therapy:
If you don’t find the term you are looking for—email us and we’ll add it to the Glossary.
Beta Blocker: A medication that slows down conduction through the heart and makes the AV Node less sensitive to A-Fib impulses.
Calcium Channel Blocker: A medication that prevents or slows the flow of calcium ions into smooth muscle cells such as the heart. This impedes muscle cell contraction, thereby allowing blood vessels to expand and carry more blood and oxygen to tissues.
NOAC: NOAC stands for Novel Oral AntiCoagulants. NOACs are alternatives for vitamin K antagonists (e.g., Warfarin) for stroke prevention in patients with atrial fibrillation.
“Pill-in-the-Pocket” Treatment: For Paroxysmal A-Fib patients. When an A-Fib attack occurs, the patient takes an antiarrhythmic med (flecainide, propafenone, etc.) to return to normal sinus rhythm.
Rate Control Medications: Drug therapy that attempts to control your heart rate (ventricular beats), but leave the upper chambers (atria) of your heart in A-Fib.
Rhythm Control Medications: Drug therapy that uses rhythm control drugs, called antiarrhythmics, to try to stop A-Fib and make the heart beat normally.

By Steve S. Ryan, PhD. This post was originally published July 15, 2016.
Your first experiences with Atrial Fibrillation have changed your life in a number of ways. As a former A-Fib patient (cured since 1998) I highly recommend these items when first diagnosed with this beast called ‘Atrial Fibrillation’.
My Top 5 Recommendations for the Newly Diagnosed
These are the products I recommend (and use) along with a Bonus: a good medical dictionary. These items are available from many online sources, but I’ve made them easy to order the entire list by making a ‘Wish List’ on Amazon.com: Steve Ryan’s A-Fib Survival Kit for the Newly Diagnosed,(Note: Use our Amazon portal link, and your purchases help support A-Fib.com.)
Most A-Fib patients are deficient in Magnesium (Mg). While Magnesium (Mg) is one of the main components of heart cell functioning, it seems to be chronically lacking in most diets.
One form of easily absorbed magnesium is Magnesium glycinate, a chelated amino acid. Look for the label ‘Albion Minerals’ designed to limit bowel sensitivity. Dosage: 600-800 mg daily in divided dosages (meals and bedtime). Read more about Magnesium.
Just like magnesium deficiency, A-Fib patients are usually deficient in Potassium as well. We recommend the powder in order to take the recommended dose of 1600-2400 mg per day.
Be cautious of potassium tablets. For example those listed as 540 mg ONLY contain 99 mg of Potassium. Read more about Potassium.
A-Fib can be cured! That’s the theme of this book written by a former A-Fib patient and publisher of the patient education website, A-Fib.com. Empowers patients to seek their cure. Written in plain language for A-Fib patients and their families.
Many A-Fib patients want to monitor their heart rate when exercising or doing strenuous tasks (mowing the lawn, moving equipment, etc.) This is a basic DIY model with a clear, LARGE number display of your heart rate (as a number). Requires wearing the included T31 coded transmitter chest strap.
One-button start. Includes a FT2 Getting Started Guide.
Also look at other Polar models: FT1 & RS3000X. I wore a Polar monitor when I had A-Fib, so it’s my brand of choice, but there are many other good brands.
Many A-Fib patients also suffer with undiagnosed sleep apnea. A finger Oximeter is an easy way to check your oxygen level. A reading of 90% or lower means you should talk to your doctor as you may need a sleep study.
An excellent medical dictionary, the best I’ve found for patients with Atrial Fibrillation who are conducting research into their best treatment options. Includes occasional illustrations (for fun check p. 276 for the types of fingerprint patterns).
Research verifies that the loved ones living with someone in Atrial Fibrillation may be about as stressed as actually having the condition.
In one study the partners of A-Fib patients reported a significant reduction in their quality of life, to the same degree as the patient. (Note: Most severely impaired was a couple’s sex life.)
Educate the Family, Not Just the Patient
One simple solution might be to make sure the spouse comes to office visits, particularly during the early visits around the time of diagnosis, says Dr. Bruce A. Koplan of Brigham and Women’s Hospital in Boston.
Research tells us A-Fib is just as stressful for the patient’s partner.
“Sometimes spouses come but stay in the waiting room,” he said. “But I don’t think that’s a good idea because they’re suffering too.”
Educational programs and other interventions to eliminate some of the unknowns may relieve the anxiety for the patient and their partner leading to improved quality of life for both.
Get all Your Loved Ones Involved
One of the most frequently asked questions I get is from the patient’s partner: “What can I do for my spouse during an A-Fib attack?”
Perhaps, just as important, A-Fib patients should be asking “How can I help my family cope with the stress and anxiety of my Atrial Fibrillation?”
A Momentary Pause: When I talk with an A-Fib patient, I always ask how their spouse or partner is doing―how they are coping. This often elicits a momentarily pause while the patient stops and ponders the impact of A-Fib on their family.
My best advice to patients is to get all your loved ones involved! Knowledge is empowering and reduces stress and anxiety.
In addition, for your family’s peace of mind, learn Why & How to Create Your ‘A-Fib Episode Action Plan’. During an A-Fib attack, an A-Fib Action Plan with specific steps is reassuring and helps everyone stay calm. Your family will be confident they’re supporting you in taking the right action at the right time.
Discuss your A-Fib Action Plan with your loved ones and answer their questions. Post a copy in a prominent place where your family can find it easily.

In the US, we’ve been conditioned to think, “if we’re sick, just take a pill”.
When you have Atrial Fibrillation, anti-arrhythmic drug (AAD) therapy is certainly better than living a life in A-Fib. It can be useful for many patients.
And according to Dr. Peter Kowey, Lankenau Heart Institute (Philadelphia, PA), while anti-arrhythmic therapy is not perfect, it can improve quality of life and functionality for a significant percentage of A-Fib patients.
P. Kowey MD
Dr Kowey is an internationally respected expert in heart rhythm disorders. His research has led to the development of dozens of new drugs and devices for treating a wide range of cardiac diseases.
He cautions, though, that A-Fib anti-arrhythmic drugs are just a stopgap measure. The problem is they don’t deal with the underlying cause. And are seldom a lasting cure for A-Fib.
“An anti-arrhythmic drug is a poison administered in a therapeutic concentration. Like most meds, anti-arrhythmic drugs, (AADs), are a trade-off between the unnatural and possible toxicity with the power to alleviate our A-Fib symptoms.”
Did “an anti-arrhythmic drug is a poison” set off alarm bells for you?
In general, anti-arrhythmic drugs are toxic substances which aren’t meant to be in our bodies―so our bodies tend to reject them.
For more, see our full article with Dr. Kowey’s insights, Eleven Things I Know About A-Fib Drug Therapy. It’s based on his 2014 American Heart Association (AHA) Scientific Session presentation.
Look Beyond the Typical AAD Therapy
Today’s anti-arrhythmic drugs have mediocre success rates (often under 50%).
Beyond AAD Therapy
Many patients often experience unacceptable side effects. Many just stop taking them. And when they do work, they tend to lose their effectiveness over time.
According to Drs. Irina Savelieva and John Camm of St. George’s University of London:
“The plethora of antiarrhythmic drugs currently available for the treatment of A-Fib is a reflection that none is wholly satisfactory, each having limited efficacy combined with poor safety and tolerability.”
These drugs don’t cure A-Fib but merely keep it at bay. Most Atrial Fibrillation patients should look beyond the typical antiarrhythmic drug therapy.
Since the beginning of A-Fib.com, we have answered thousands of patient’s questions—many times the same questions. Perhaps the same questions you may have right now.
Tony Hall, Evansville, IN, was 54 years old when he develped Atrial Fibrillation in January 2014. After confirming his diagnosis at the hospital, he wrote:
“I sit in the passenger seat feeling like a pet heading to a kennel. Suddenly things are different. I no longer have that “healthy as a horse” attitude.”
He started drug therapy. Then came a cardioconversion, but that didn’t keep him in normal sinus rhythm for long. He was in and out of A-Fib, and by August was in persistent A-Fib.
Learning His Treatment Options
Tony didn’t passively accept everything he was hearing from doctors and others.
He and his wife, Jill, read as much as they could and critically waded through the information they found. (I’m continually amazed at how much mis-information there is about A-Fib on the internet and in the media.)
5-months post-ablation, Tony and Jill after 10K race.
After doing his research, educating himself about treatment options and learning what his health insurance would cover, he chose to have a catheter ablation at the Mayo Clinic in December 2014.
During his three month blanking period, he had some sporadic fluttering and early on a couple of brief A-Fib episodes.
Off all medication and A-Fib-free, in March 2015 he completed a 10K race beating his time from the previous year by a fraction.
Becoming his Own Best Patient Advocate
Tony and Jill are great examples for all A-Fibbers of how to become your own best patient advocate. He rejected endless trials of various drug therapies. Instead he opted for a catheter ablation just shy of a year after his initial A-Fib diagnosis.
In his A-Fib story, he shares this advice to others considering a catheter ablation:
“Make sure, if you desire to have an ablation, that your reasoning is sound and that you have a good argument as to why drug therapy is not the way you want to go.
Having an ablation as front line treatment for A-Fib is not embraced by every EP, and many are reluctant to ablate until drug therapy has failed.
Be persistent and move on [to another doctor] if you are met with resistance.”
Last updated: January 13, 2022—When you have A-Fib and you’re taking a blood thinner or other medications, you may want to carry details of your specific medical history.
From the simple printed card to products with an integrated USB drive, there are many ways to carry your emergency history with you these days.
Beyond the familiar styles of metallic Medic Alert ID bracelets and necklace pendants, there are products using newer materials like waterproof foam, Duro silicone and plastic. And products linking to centralized, password protected data storage services.
We’ve reviewed dozens of products to offer you an updated sampling of the available options. (For each product, we’ve included a hyperlink so you can easily get more information.)

Review and Update the Contents Regularly
Whichever method(s) you use to carry your emergency medical information, don’t forget to review and update the contents regularly. For example, when you change doctors, when you start (or stop) a medication, or if you have a medical emergency or surgical procedure.
Knowing you have up-to-date medical information will give you peace of mind.
Additional thought: Consider your spouse and other family members. Should they also carry their medical emergency ID information?

There’s a growing body of evidence linking atrial fibrillation with early onset of dementia. New cases of dementia are diagnosed every four seconds. The number of people with dementia is also expected to triple worldwide to an estimated 140 million by 2050.
Most Feared:When 65+ year olds were asked what disease or condition they were most afraid of getting, 56 percent cited memory-robbing dementia.
Good News: A bit of good news is that the prevalence rate of dementia has declined in some countries, including in the US. And researchers think it may in part be due to increases in levels of education, which seems to protect people from getting dementia.
For a disease many of us fear, the message is hopeful: Dementia is not necessarily inevitable.
While both Atrial fibrillation and dementia have been linked to aging, neitheris a normal part of growing older.
Reducing Your Risk of Developing Dementia
You CAN influence or avoid developing dementia. Review these articles to learn more about the link between Atrial Fibrillation and dementia:
Atrial Fibrillation and Dementia: Neither is a normal part of growing older.
What doesn’t work: current drugs, even statins, don’t work or have mixed results in preventing dementia.
What does work: Catheter ablation to eliminate your Atrial Fibrillation. Patients who get a catheter ablation have long-term rates of dementia similar to people without A-Fib. (This result holds regardless of their initial CHADS2 score.)
Don’t Settle. Seek your A-Fib cure:To decrease your increased risk of dementia, your goal should be to get your A-Fib fixed and get your heart beating normally again. We can’t say it enough:
Do not settle for a lifetime on meds. Seek your A-Fib cure.

I received a very distressing email from a reader, Kenny, who was worried about his prescribed medications. He wrote that he just had a cardioversion a week ago and is back in A-Fib (unfortunately that’s not uncommon). Alarm bells went off in my head when I read:
“My doctor just prescribed me amiodarone 200mg, 4x a day…I’m a little concerned about the amiodarone and all the side effects!”
“I’m also on Digoxin…Xarelto and aspirin… .”
“I can’t get my doctor’s office or doctor to call me back! Reluctant to start amiodarone until I can talk to someone!”
Drugs Therapies Concerns
Ding, Ding, Ding!I am deeply concerned for him. The doctor prescribing these drugs is in internal medicine, not a cardiac electrophysiologist. While Kenny and I continue to exchange emails, here’s some highlights from my first reply:
• Amiodarone is an extremely toxic drug, and this dosage is 4x the normal dose. • You must get a second opinion ASAP! (consult a cardiac electrophysiologist) • Digoxin is also a dangerous drug not normally prescribed for A-Fib patients. • It’s very unusual to prescribe both Xarelto and aspirin.
Time to Change Doctors?And lastly, I wrote him that if your doctor or his office isn’t calling you back, that’s a sign you should look for a new doctor (don’t be afraid to fire your doctor). You need good communication when you’re in A-Fib and trying to find a cure.
I’m glad Kenny reached out to me so we can get him on the right A-Fib treatment plan for him and his treatment goals.
Ask These Questions Before Starting a Prescription Drug
Download the Free Worksheet
Before starting any prescription drug for your Atrial Fibrillation, you should ask what it’s for and why you should take it.
1. Why am I being prescribed this medication? 2. What are the alternatives to taking this medication? 3. What are the side effects of this drug? 4. Are there any precautions or special dietary instructions I should follow? 5. Can it interfere with my other medications?. 6. How long before I know if this drug is working? 7. How will I be monitored on this drug? How often? 8. What happens if this drug doesn’t work? 9. What if my A-Fib symptoms become worse? 10. If I don’t respond to medications, will you consider non-pharmaceutical treatments (such as a catheter ablation)?
Research and Learn About Any Prescription Drug
You can do your own research about a specific medication and if it’s the right one for you.
Download our free worksheet: ’10 Questions to Ask Before Taking Any Medication’. Take a copy to your office visits.
Your research and the answers to these 10 questions should help you decide about taking a new prescription drug. Remember, it’s your heart, your health. Taking medications is a decision you should make in partnership with your doctor.
“Don’t let anyone—especially your doctor—tell you that A-Fib isn’t that serious…or you should just learn to live with it…or to just take your meds.”
From Beat Your A-Fib: The Essential Guide to Finding Your Cure
Research studies tell us the longer you have Atrial Fibrillation, the harder it can be to cure it. A-Fib patient Daniel Doane, Sonora, CA, shares his insights:
Daniel D.
“I didn’t realize how continued A-Fib so drastically remodels your heart. ‘A-FIB BEGETS A-FIB’ was the phrase that brought it home to me.
Every instance of A-Fib changed my heart, remodeled the substrate, and made it more likely to happen again. Get your A-Fib taken care of. It won’t go away. It may seem to get better, but it will return.”
Lessons Learned: After eight years with A-Fib, Daniel had a successful Totally Thoracoscopic (TT) Mini-Maze operation. In his personal story in Beat Your A-Fib, he offers this advice to others with A-Fib:
“Get a catheter ablation or a mini-maze procedure, whichever best suits your situation. I wish I had had this done sooner. I personally think that the sooner a person has a procedure, the better off they are.”
Due to the increased use of medical marijuana in California and other states, we should soon be getting more data on marijuana’s effects on Atrial Fibrillation.
Several readers with A-Fib have emailed me to share their experiences and observations with marijuana. There seems to be a lot of interest every time I write about this topic.
How about you? I’d love to get more first-hand feedback from A-Fib users. Please email me.
First-Hand Experiences: A-Fib and Medical Marijuana
Jim, an A-Fib patient, has kindly shared his personal use of marijuana and how it helps him. He has tried various meds, cardioversion, and had a failed ablation. He owns his own business in California and is under a lot of stress.
♥ JIM:“Because of all of this, I was having trouble sleeping and was getting very stressed out. But instead of taking something pharmaceutical, I turned to medical marijuana. It changed my life. I come home at night, have some marijuana edibles, and the stress goes away. I sleep wonderfully at night, waking up fresh and ready for another day.
I told my doctor who understands. He says that marijuana edibles shouldn’t have anything to do with A-Fib, and that I can continue to take them.”
On the other hand, John writes that:
♥ JOHN:“99% of his A-Fib attacks occurred while under the influence of marijuana.”
And others add their experiences:
♥ JONATHAN:“I tried a tiny bit of brownie for the first time since being diagnosed with A-Fib (occasional episodes). It was OK until about two hours later. I went into A-Fib and, a bit later, came the closest I ever have to blacking out. I don’t think it’s for me anymore.”
You can join the discussion, too. If you have used marijuana to help with your A-Fib symptoms, email me and share your experience.
♥ WILLIAM:“The A-Fib ablation has been very successful, except the two times that I went into A-Fib after smoking marijuana. I’m a lifelong recreational marijuana smoker, also smoke to relieve the pain from six surgeries on my right arm. Both times that I’ve gone into A-Fib since my last ablation have been after smoking marijuana. After the latest episode I’ve quite smoking marijuana because of the evidence that it can lead to A-Fib.”
♥ SCOTT: “I am currently 55 years old and have been through 15 cardioversions due to A-Fib. I smoked marijuana pretty much daily and noticed that, when I smoked, my heart rate went up. So, I stopped smoking altogether. Since quitting smoking marijuana 7 years ago, I have not had a single case of going into A-Fib. I’m positive that the two are related.”
Scott added that he also stopped drinking which helped. He used to drink a six pack daily.
