"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

"Your book [Beat Your A-Fib] is the quintessential most important guide not only for the individual experiencing atrial fibrillation and his family, but also for primary physicians, and cardiologists."

Jane-Alexandra Krehbiel, nurse, blogger and author "Rational Preparedness: A Primer to Preparedness"


"Steve Ryan's summaries of the Boston A-Fib Symposium are terrific. Steve has the ability to synthesize and communicate accurately in clear and simple terms the essence of complex subjects. This is an exceptional skill and a great service to patients with atrial fibrillation."

Dr. Jeremy Ruskin of Mass. General Hospital and Harvard Medical School

"I love your [A-fib.com] website, Patti and Steve! An excellent resource for anybody seeking credible science on atrial fibrillation plus compelling real-life stories from others living with A-Fib. Congratulations…"

Carolyn Thomas, blogger and heart attack survivor; MyHeartSisters.org

"Steve, your website was so helpful. Thank you! After two ablations I am now A-fib free. You are a great help to a lot of people, keep up the good work."

Terry Traver, former A-Fib patient

"If you want to do some research on AF go to A-Fib.com by Steve Ryan, this site was a big help to me, and helped me be free of AF."

Roy Salmon Patient, A-Fib Free; pacemakerclub.com, Sept. 2013


FAQ Minerals & Supplements: Can Anemia Cause Atrial Fibrillation?

FAQ Minerals Deficiencies: Anemia 

7. “I’m anemic. Is too little iron in the blood (anemia) a cause of Atrial Fibrillation? Any advice on how A-Fib patients can deal with iron deficiency?”

A-Fib patient, Sally Mertens, wrote about iron deficiency and offers this advice:

“Based on my experience dealing with chronic A Fib, I would stress the importance of having ferritin [iron storage protein] level checked.

My doctor (gynecologist, not my cardiologist!) figured out that my chronic A-Fib might be related to my low ferritin level which was at 9. After only 6 weeks of taking Repliva (82 mg/day iron), my ferritin level was up to 29 and my A Fib had stopped. (Another over-the-counter iron supplement is Floradix.)

I haven’t had one A Fib attack since I started the Repliva. I have concurrently stopped donating blood (which I was doing as frequently as possible) and began eating beef—at least 8 ounces per week (after 3 years as a vegetarian).

Normal serum ferritin (SF) ranges differ by gender, ethnicity and age. The ideal serum ferritin range for adults is 50-150ng/mL

My GYN would like to see my ferritin level at about 50 and told me it would take about 6 months for me to get my blood “stores” back to normal.

I feel extremely lucky and grateful that when I moved to a new town, I got referred to a GYN who was well aware of the link between anemia in pregnancy and heart conditions.

(As a footnote, every time I donated blood, I passed the Red Cross hemoglobin test. My GYN understood how that was possible, but I didn’t understand the explanation well enough to share it with you here.)

I’m well past child-bearing age and thus, as a precaution, my GYN also sent me for a colonoscopy to rule out internal bleeding as a factor in my low ferritin.”

From another A-Fib.com reader:

Mike writes that taking a product like Geritol boosts his red blood cells and improves his heart valve problems and his A-Fib.

Lesson Learned: A-Fib patients should ask their doctor to verify they have a Normal serum ferritin (SF) level.

FAQs: Mineral Deficiencies & Supplements for a Healthy Heart

FAQs: Mineral Deficiencies & Supplements for a Healthy Heart

A-Fib patients often look for non-drug approaches to ease or prevent the symptoms of their Atrial Fibrillation. Here we share answers to the most often asked questions about minerals deficiencies and the use of supplements.

1. I’m scared of getting dementia. Can the right minerals help? I’ve read about the link with A-Fib. What does research reveal about this risk?

2.How can I tell if I’m lacking in Vitamin D? I’m concerned because Vitamin D deficiency has been tied to both A-Fib and Dementia. What is a normal level of Vitamin D?

3. “I have annoying PVCs and PACs with my A-Fib. Are there natural remedies to reduce these extra beats and palpitations? My doctor says to ignore them.”

4. I tried to talk with my doctor about magnesium and other nutritional supplements. ‘There’s no proof that they work,’ was his response. Why are doctors so opposed to nutrition as a way of helping A-Fib.”

5. The supplement BCAA+G helps builds muscle. Is it a natural remedy that could help my A-Fib? Are A-Fib patients BCAA-deficient?

6. What’s the best way to take supplements—at the same time each day or spread throughout the day? In one lot or in divided doses?

7. “I’m anemic. Is too little iron in the blood (anemia) a cause of Atrial Fibrillation? Any advice on how A-Fib patients can deal with iron deficiency?”

8. “Can excess iron in the blood (Iron Overload Disease, IOD) cause Atrial Fibrillation? How do I know if I have IOD? What can I do about it?

9. “Where can I find reliable, unbiased research and information on specific vitamins and supplements? (I want an independent resource, not some site trying to sell me their products.)

10. “What does ‘chelate’ or ‘chelated formulas’ mean when talking about vitamin and minerals? Is it important?

11. “Regarding Magnesium, can supplementing and restoring Mg to healthy levels reverse my A-Fib? I’m about to schedule a catheter ablation. But if supplementing can cure my A-Fib, why do an ablation?

12. “Can I take the supplement CoQ10 while on Eliquis for Atrial Fibrillation? On your site it says CoQ10 could be helpful. But on my bottle of CoQ10, it says “do not take if you are on blood thinners.

13. “I’m taking Eliquis for my risk of A-Fib stroke. I’m interested in the supplement, Krill Oil, that has natural blood thinning properties. Is It OK to take Krill Oil along with Eliquis?

FAQs Coping With Your A-Fib Day-to-Day Issues

FAQs A-Fib afibFAQs Coping With Your Atrial Fibrillation: Day-to-Day Issues

Coping with your Atrial Fibrillation means a patient and their family have many and varied questions. Here are answers to the most frequently asked questions about dealing with the day-to-day issues of having Atrial Fibrillation. (Click on the question to jump to the answer.)

1.  I like my cardiologist, but he has not talked about me seeing an Electrophysiologist. Should I ask for a second opinion from another cardiologist?”
2. Is there any way to predict when I’m going to have an A-Fib attack?”
3. Should I exercise when in A-Fib or skip it and rest? Can I damage my heart if I exercise in A-Fib?”
4. How long do I have before I go into chronic or permanent A-Fib? I know it’s harder to cure. My A-Fib episodes seem to be getting longer and more frequent.”
5. They want to do an Atrial Flutter-only ablation, will that help if I possibly have A-Fib as well?”
6.  Is smoking medical marijuana or using Marinol going to trigger or cause A-Fib? Will it help my A-Fib?
7.  “During an A-Fib episode, when should I call paramedics (911 in the US) and/or take my husband to the hospital? I’m petrified. I need a plan.”
8. I have a lot of extra beats and palpitations (PVCs or PACs) They seem to proceed an A-Fib attack. What can or should I do about them?”
9.   “How do I know which is the best A-Fib treatment option for me?”
10. When my husband has an Atrial Fibrillation episode, what can I do for him? How can I be supportive?”
11. How can I tell when I’m in A-Fib or just having something like indigestion?”
12.What kind of monitors are available for atrial fibrillation? Is there any way to tell how often I get A-Fib or how long the episodes last?”
13. I’m an athlete with A-Fib and have a naturally slow heart rate. My doctor says I need a pacemaker because my heart rate is too slow.”
14. Can excess iron in the blood cause Atrial Fibrillation? How do I know? If I have Iron Overload Deficiency (IOD), what can I do about it?”
15. Can too little iron in the blood (Anemia) cause Atrial Fibrillation? What can I do about iron deficiency?”
16.Is it possible to have a single A-Fib attack and not have any others? I had a single episode of A-Fib and was successfully converted in the ER with meds.”
17. “My mom is 94 with A-Fib. Are there consumer heart rate monitors she can wear to alert me at work if her heart rate exceeds a certain number?”
18. Can I have A-Fib when my heart rate stays between 50-60 BPM? My doctor tells me I have A-Fib, but I don’t always have a rapid heart rate.”
19. I’m in Chronic A-Fib. Can I improve my circulation, without having to undergo a Catheter Ablation or Surgery?”

20. “In one of your articles it said that having an ablation was better than living in A-Fib. I’ve been taking 75 mg of propafenone 3X/day for seven years and have only had 5 A-Fib attacks in 7 years. If your article means all types of A-Fib [including Paroxysmal], then I will consider an ablation.

21. “Both my uncles and my Dad have Atrial Fibrillation. I’m 50 years old and so far I don’t have A-Fib (yet), but I’m worried. How can I avoid developing A-Fib? Can dietary changes help? Or lifestyle changes?

22. In case I have a stroke, what does my family need to know to help me? (I’m already on a blood thinner.)  What can I do to improve my odds of surviving it?”
