Center of Excellence
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.
