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,

"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."

Castle Connolly ‘TOP DOCTORS’ Included in our A-Fib.com Directory of Doctors

Published April 25, 2016

Last updated: August 15, 2026 | When using our A-Fib.com Directory of Doctors and Medical Centers, you may see an additional qualification after some doctor’s names: “Listed in Castle Connolly TOP DOCTORS.”

An Online Source We Trust: Castle Connolly TOP DOCTORS are first peer-nominated by surveying tens of thousands of practicing clinicians across the U.S. Then the research team, guided by the Castle Connolly Advisory Board, screens each provider and confirms whether each meets Castle Connolly standards. (Continue reading to learn about the screening criteria.)

Unlike other ‘find a doctor services’, No one can pay to be a Castle Connolly Top Doctor. Each provider has been hand selected.

Castle Connolly only features the top 7% of doctors in the U.S. The results are truly the country’s Top Doctors. (Unfortunately, this service only covers U.S. doctors.)

Note: You can refer to Castle Connolly TOP DOCTORS for any medical specialty, including DENTISTS.
They also rate TOP HOSPITALS and offer a number of distinctions including Top Black Doctors, Exceptional Women in Medicine, Top AAPI Doctors, Top LGBTQ+ Doctors, and Top Hispanic and Latino Doctors.

TOP DOCTERS added to A-Fib.com Directory.

‘TOP DOCTORS’ included in A-Fib.com Directory.

Castle Connolly’s TOP EPs: To add Castle Connolly top-rated Electrophysiologists (EPs) to our own Directory, we first combed through the Cardiologists listed in ‘America’s Top Doctors’, then manually selected those who specialize in Electrophysiology (EP).

Important: Just like Steve’s Directory of Doctors and Medical Centers, Castle Connolly Top Doctors cannot request or pay to be listed.

Caution: Don’t rely on any single source of recommendations (including our own directory). You still need to do your own due diligence when selecting a doctor. For guidance, see our article: Finding the Right Doctor for You.
