The Heart Rhythm Institute of Arizona
John F. Beshai, MD, FACC, FHRS

Dr. Beshai is an internationally renowned and respected heart rhythm specialist. His most notable attribute, however, is his ability to connect and communicate with people. As a teacher, he understands that every training level has very different degrees of fundamental knowledge and understanding from the most basic medical student to the most advanced training level of cardiac electrophysiology fellow. The ability to understand these differences and tailor education based on the degree of training translates to the ability to naturally connect with patients on their level.

Keeping Your Heart in Rhythm,One Beat At A Time

What Makes Us Different?

Dr. Beshai believes in practicing medicine the “old-fashioned way.” From the moment you step into the office, you will immediately feel that YOU are the priority. Suffering from cardiovascular diseases, especially rapid and irregular heartbeats, can be terrifying. You may have been told that you need an urgent ablation procedure or perhaps implantation of a medical device like a pacemaker or defibrillator. It’s this kind of blanket diagnosis that separates any arrhythmia doctor from the right doctor who will not only provide care but actual solutions!

Dr. Beshai has more than 15 years of experience in academic medicine, serving as staff and faculty at prestigious medical institutions including Emory University, University of Chicago, and more recently the Mayo Clinic. Over the years he has trained hundreds of medical trainees including medical students, residents, cardiology fellows, and cardiac electrophysiology fellows. His experience includes keeping up with the most advanced approaches to patient care that incorporate the current guidelines as well as state-of-the-art techniques.

At the Heart Rhythm Institute of Arizona, you can expect personalized care where you are empowered to make your own decisions based on a total understanding of your condition and all of the available options.
