Ali R. Keramati, MD

Dr. Ali R. Keramati is Program Director of the Clinical Cardiac Electrophysiology Fellowship at Lankenau Medical Center and an attending electrophysiologist within Main Line Health. He specializes in complex cardiac arrhythmia management, catheter ablation, physiologic pacing, cardiac implantable electronic devices, and left atrial appendage occlusion, with particular interests in electrophysiology education, intracardiac electrogram interpretation, and innovation in pacing and mapping strategies.

Dr. Keramati completed his internal medicine residency at Yale New Haven Hospital, followed by cardiovascular disease fellowship training at Johns Hopkins Hospital, where he also completed advanced fellowship training in clinical cardiac electrophysiology. He is board certified in Internal Medicine, Cardiovascular Disease, and Clinical Cardiac Electrophysiology.

As Program Director, Dr. Keramati is focused on developing electrophysiologists who combine technical excellence with deep physiologic understanding and thoughtful clinical decision-making. His educational interests center on advancing the teaching of intracardiac electrogram interpretation and procedural reasoning in electrophysiology training programs. He has been actively involved in national educational and research initiatives, including service with the U.S. Food and Drug Administration Medical Device Advisory Committee and the American College of Cardiology NCDR EP Device Implant Registry Steering Committee.

Dr. Keramati has authored numerous peer-reviewed publications and invited lectures in cardiac electrophysiology, with academic interests spanning physiologic pacing, atrial fibrillation ablation, device therapy, and electrophysiology education. He is committed to fostering a collaborative, intellectually rigorous fellowship environment that emphasizes curiosity, autonomy, and mastery of both procedural and cognitive aspects of electrophysiology.
