Vivek Y. Reddy, MD is Director of Cardiac Arrhythmia Services for The Mount Sinai Hospital and the Mount Sinai Health System, and The Leona M. and Harry B. Helmsley Charitable Trust Professor of Medicine in Cardiac Electrophysiology at the Icahn School of Medicine at Mount Sinai. Dr. Reddy is one of the nation’s premier cardiac electrophysiologists. He leads a team of physician-scientists who are developing and testing advanced therapies for cardiac arrhythmias and heart failure, including catheter ablation for atrial fibrillation and ventricular tachycardia, and device therapies for stroke prevention. Under his leadership, Mount Sinai is the lead investigational site for many multinational clinical trials exploring new arrhythmia procedures and technologies, most recently pulsed field ablation to treat atrial fibrillation. Moreover, in 2014, he implanted the world’s first miniature leadless pacemaker, as well as the first leadless pacemaker in the United States at Mount Sinai Hospital.
