John F. Beshai, MD

Associate Professor of Medicine

Director, Pacemaker and Defibrillator Services

Director, Cardiac Electrophysiology Fellowship

John F. Beshai, MD, is an expert in cardiac electrophysiology, an area of medicine focused on the treatment of heart rhythm problems (arrhythmias). Dr. Beshai provides the full range of treatment options, from radiofrequency catheter ablation for atrial fibrillation, ventricular tachycardia and supraventricular tachycardia, to pacemaker and defibrillator implantation to control irregular heartbeats. He is certified as a diplomat by the American Board of Internal Medicine in cardiovascular disease and clinical cardiac electrophysiology. Currently, he serves as a manuscript reviewer for major cardiology journals, including Journal of the American College of Cardiology, Heart Rhythm, Journal of Cardiovascular Electrophysiology, Pacing and Clinical Electrophysiology, American Journal of Cardiology, and the American Heart Journal.

A respected scientist, Dr. Beshai’s clinical research interests are focused on device therapy in patients with congestive heart failure (CHF) and sarcoidosis. Additionally, he is involved in multiple studies developing new technologies and approaches to radiofrequency catheter ablation of complex arrhythmias, including atrial fibrillation and ventricular tachycardia.

Dr. Beshai served as the national principal investigator and Steering Committee chairman for the Cardiac Resynchronization Therapy in Heart Failure and Narrow QRS complexes (RETHINQ) trial, and was the first author of its publication in the New England Journal of Medicine. He has been invited nationally and internationally to speak on his research and specialty interests.

Read More About Dr. Beshai

Dr. Beshai is featured in a story about Lyal Lauth. Tests revealed that Lyal's mitral valve needed to be replaced again. With additional health problems, his complex case needed the expertise of several University of Chicago specialists.

Read about the comprehensive treatment plan Dr. Beshai and a team of UChicago Medicine physicians developed for Kathleen Colvin, who had congestive heart failure, atrial fibrillation and other conditions--and was at risk for needing kidney dialysis or a transplant.
