"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


FAQs A-Fib Drug Therapy: Will the Beta-Blocker, Atenolol, Stop My A-Fib?

 FAQs A-Fib Drug Therapy: Atenolol

Drug Therapies for Atrial Fibrillation, A-Fib, Afib

3. I take atenolol, a beta-blocker. Will it stop my A-Fib.”

Not usually. Beta-blockers like atenolol, in addition to calcium channel blockers, and digitalis compounds are all rate-control medications. They attempt to control your heart rate (ventricular beats), but leave your heart in A-Fib. “In fact, these (rate control) drugs, which are quite valuable in achieving ventricular rate control, have not been shown in placebo-controlled studies to restore sinus rhythm.”

However, we all react somewhat differently to meds. A drug that doesn’t work for one person may be very effective for another.

If you are under the impression that atenolol or other rate control drugs will stop your A-Fib, it might be wise to check with your doctor or get a second opinion.

Drug Therapies for Atrial Fibrillation

Atrial Fibrillation patients often search for unbiased information and guidance about medicines and drug therapy treatments. These are answers to the most frequently asked questions by patients and their families. (Click on the question to jump to the answer.)

1. Which medications are best to control my Atrial Fibrillation?” “I have a heart condition. What medications work best for me?

2. “Is the “Pill-In-The-Pocket” treatment a cure for A-Fib? When should it be used?”

3. “I take atenolol, a beta-blocker. Will it stop my A-Fib.”

4. I’ve been on amiodarone for over a year. It works for me and keeps me out of A-Fib. But I’m worried about the toxic side effects. What should I do?”

5. Should everyone who has A-Fib be on a blood thinner like warfarin (Coumadin)?”

6. Which is the better anticoagulant to prevent stroke—warfarin (Coumadin) or aspirin?

7. What’s the difference between warfarin and Coumadin?

8. I’m on warfarin. Can I also take aspirin, since it works differently than warfarin? Wouldn’t that give me more protection from an A-Fib (ischemic) stroke?

9. “What are my chances of getting an A-Fib stroke?

10. “I’m worried about having to take the blood thinner warfarin (brand name Coumadin). If I cut myself, do I risk bleeding to death?

11. “I am on Coumadin (warfarin) to thin my blood and prevent A-Fib blood clots. Do I now need to avoid foods with Vitamin K which would interfere with the blood thinning effects of Coumadin?” UPDATED

12. “The A-Fib.com web site claims that an A-Fib stroke is often worse than other causes of stroke. Why is that? If a clot causes a stroke, what difference does it make if it comes from A-Fib or other causes? Isn’t the damage the same?

13. “I just had an Electrical Cardioversion. My doctor wants me to stay on Coumadin for at least one month. Why is that required? They mentioned something about a “stunned atrium.” What is that?

14. Are natural blood thinners for blood clot treatment as good as prescription blood thinners like warfarin?”

15. “How long do I have to be in A-Fib before I develop a clot and have a stroke?

16. I have to be on aspirin for stroke prevention. Which is better—the low-dose baby aspirin (81 mg) or a high dose (325 mg)? Should I take the immediate-release (uncoated) or the enteric-coated aspirin?

17. I don’t want to be on blood thinners for the rest of my life. I’ve had a successful catheter ablation and am no longer in A-Fib. But my doctor says I need to be on a blood thinner. I’ve been told that, even after a successful catheter ablation, I could still have “silent” A-Fib—A-Fib episodes that I’m not aware of.  Is there anything I can do to get off of blood thinners?

18. “My last cardiologist had me on Pradaxa. My new cardiologist wants me to switch to Eliquis. Is Eliquis easier to deal with if bleeding occurs?

19. “My doctor told me about the Tikosyn drug option that I want to consider in getting rid of my 5-month-old persistent A-Fib. That seems like something that should be discussed on your web site.

20. “I hate taking Coumadin. Is there a way to get off blood thinners all together? I know I’m at risk of an A-Fib stroke.”

21. “I”ve read about a new anticoagulant, edoxaban, as an alternative to warfarin (Coumadin) for reducing risk of stroke. For A-Fib patients, how does it compare to warfarin? Should I consider edoxaban instead of the other NOACs?

22. “Do you have information about Hormone Replacement Therapy (HRT) and if it might help or hinder my atrial fibrillation?

23. Are Anticoagulants and blood thinners the same thing? How do they thin the blood?

24. I have A-Fib, and my heart doctor wants me to take Xarelto 15 mg. I am concerned about the side effects which can involve death. What else can I do?

25. “Is the antiarrhythmic drug Multaq [dronedarone] safer than taking amiodarone? How does it compare to other antiarrhythmic drugs?”
