Overview

Dr. Ivan C. Ho is currently the Director of Cardiac Electrophysiology in Keck Medicine’s Cardiac and Vascular Institute, the Program Director of the Clinical Cardiac Electrophysiology Fellowship and Clinical Associate Professor of Medicine at the Keck School of Medicine of USC.

Dr. Ho grew up in Hong Kong, and completed his undergraduate studies at Harvard College, where he received his A.B. summa cum laude in Chemistry. After receiving his M.D. from Harvard Medical School, Dr. Ho completed internship, residency, cardiology and clinical cardiac electrophysiology fellowships at Massachusetts General Hospital in Boston. Following his training in 2008, he joined Los Angeles Cardiology Associates, a large academic cardiology practice based at the Good Samaritan Hospital, and became the Medical Director of its Complex Ablation Program, and the Associate Program Director of Harbor UCLA-Good Samaritan Hospital EP fellowship program. Prior to joining USC in 2019, he has already trained over 20 EP fellows and many visiting fellows from China, Korea, Japan and Hong Kong. Dr. Ho has an active electrophysiology practice in Los Angeles and the San Gabriel Valley, and has started Complex Ablation Program at other hospitals, having served as the Director of Electrophysiology at Garfield Medical Center and the Assistant Director of Atrial Fibrillation Research at Cedars-Sinai Heart Institute.

Dr. Ho is a cardiac electrophysiologist whose subspecialty expertise includes catheter ablation for complex cardiac arrhythmias using the latest mapping and imaging technology, device implantation and evaluation of patients with arrhythmias. He is particularly interested in catheter ablation of atrial fibrillation and ventricular tachycardia, and implantation of advanced cardiac devices for heart failure. Academically, Dr. Ho is an avid clinical educator. Besides training his own EP fellows at USC, he speaks regularly at national and international meetings, as well as in training courses targeted at EP fellows and early-career electrophysiologists, both in the theory and procedural practices of clinical electrophysiology.

His research interests include intracardiac imaging during complex ablation procedures, mapping techniques and algorithms in persistent atrial fibrillation, and optimization of EP laboratory workflow to improve care efficiency. He is a clinical investigator in a number of large, multi-center research studies on new catheter technology and cardiac devices, and is part of a large AF ablation national registry.
