Jim Cheung, MD, FACC, FHRS is Associate Professor of Medicine, Director of the Cornell Cardiac Electrophysiology Fellowship Program,and Director of Clinical Electrophysiology Research. A native New Yorker and valedictorian from the Bronx High School of Science, he graduated summa cum laude in Biochemical Sciences from Harvard University in 1995 and received his medical degree at Harvard Medical School in 1999. He completed his internship and residency training at the Massachusetts General Hospital. Dr. Cheung performed his fellowship training in cardiology and cardiac electrophysiology at Cornell University Medical Center.

Dr. Cheung specializes in the treatment of all heart rhythm disorders. His areas of expertise include catheter ablation treatment of atrial fibrillation and complex atrial tachycardia (with specialization on the use of near-zero X-ray exposure techniques), treatment of ventricular arrhythmias (with extensive experience in robotic magnetic navigation-guided ablation), and cardiac device implantation (with emphasis on His bundle pacing, cardiac resynchronization therapy devices and subcutaneous implantable cardioverter-defibrillators [ICDs]).

He has published numerous original papers and review articles on catheter ablation and mechanisms of atrial fibrillation and ventricular arrhythmias, outcomes of patients with device-detected atrial fibrillation, genetics of inherited ventricular arrhythmia syndromes, syncope and patterns of ICD malfunction. He was a 2011 Weill Cornell Medical College Department of Medicine Investigators Research Award Finalist.

Dr. Cheung is currently conducting research on areas including: 1) atrial fibrillation pathophysiology and ablation outcomes, 2) implantable cardiac device detection of AF, 3) inherited arrhythmia disorders and 4) ventricular tachycardia and PVC ablation with robotic magnetic navigation guidance.  He is co-founder of the Weill Cornell Cardiovascular Outcomes Research Group (CORG) whose mission is to assess the effectiveness and outcomes of cardiovascular interventions with a focus on the treatment of heart rhythm disorders and structural heart disease and the improvement of healthcare delivery.

He is site principal investigator of the MAGNETIC VT trial (ClinicalTrials.gov ID NCT02637947) comparing outcomes of patients with ventricular tachycardia undergoing catheter ablation with robotic magnetic navigation versus conventional manual approach. He is a principal study investigator of the multicenter, investigator-initiated SENSE trial (ClinicalTrials.gov ID NCT02186704) investigating AF detection using a novel ICD lead.

He is a Fellow of the American College of Cardiology and Fellow of the Heart Rhythm Society (HRS). He serves on the CCEP Program Directors Subcommittee of HRS and as the HRS Alternate Delegate to the American Medical Association. He has served as faculty speaker and moderator at the American College of Cardiology and Heart Rhythm Society scientific sessions.

Dr. Cheung was named a New York Magazine Top Doctor in Cardiac Electrophysiology in 2018. His teaching honors include: the Harvard Medical School Class of 2001 Teaching Award for mentorship of medical students, the Massachusetts General Hospital Internal Medicine Resident Teaching Award in 2002 and the NSLIJ Excellence in Teaching Award in 2008. He is fluent in Cantonese and Mandarin.
