Personal Statement

As a cardiac electrophysiologist, I feel that it is a privilege to practice at the forefront of innovative medicine. Advancements in our understanding of heart rhythm disorders have translated into new therapies that improve the quality and duration of the lives of our patients every day. At an academic institution that strives for excellence, I hope to deliver outstanding care to my patients and to make significant contributions to the field of cardiac electrophysiology by engaging in important research.


Biographical Info

Jim Cheung, MD, FACC, FHRS is Professor of Medicine, Director of Clinical Electrophysiology Research and the Cornell Cardiac Electrophysiology Fellowship Program and Associate Director of the Cardiac Electrophysiology Section at Weill Cornell Medicine. 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 New York Presbyterian Hospital - Cornell University Medical Center.

Dr. Cheung specializes in the treatment of all heart rhythm disorders. His areas of expertise include catheter ablation of atrial fibrillation (AF), complex atrial tachycardia (with specialization on the use of zero and near-zero X-ray exposure techniques), ventricular arrhythmias (with extensive experience in robotic magnetic navigation-guided ablation), and cardiac device implantation (with emphasis on His/left bundle region pacing, cardiac resynchronization therapy devices and subcutaneous implantable cardioverter-defibrillators [ICDs]). He employs a tailored patient-centered and multidisciplinary approach to the management of AF and has successfully treated patients who have failed AF treatment at other centers.

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 has published over 140 papers on original studies, review articles and editorials on the outcomes of catheter ablation of AF and ventricular arrhythmias, arrhythmia mechanisms, genetics of inherited arrhythmias, syncope and other aspects of heart rhythm disorders. Dr. Cheung is conducting research on areas including: 1) innovative AF ablation techniques and technologies, 2) novel arrhythmia devices, 3) real-world outcomes of arrhythmia therapies, 4) genetic factors on the development of arrhythmias in young patients, and 5) robotic magnetic navigation-guided ablation of complex arrhythmias. 

In a collaboration with the Weill Cornell Englander Institute of Precision Medicine, Dr. Cheung is the principal investigator of a study evaluating the role of next generation sequencing for the diagnosis and treatment of heart rhythm disorders, including atrial fibrillation, ventricular arrhythmias and sudden cardiac arrest in young patients. He is the site principal investigator of the ADVANTAGE AF pulsed field ablation (NCT05443594), NEwTON AF ablation catheter study (NCT04580914) and novel extravascular implantable-cardioverter defibrillator EV-ICD pivotal study (Clinicaltrials.gov ID NCT04060680) as well as numerous other ongoing clinical trials.

He is Chair of the American College of Cardiology (ACC) Electrophysiology Section Leadership Council, Vice-Chair of the Heart Rhythm Society (HRS) Electrophysiology Fellowship Program Directors Committee, HRS Delegate to the American Medical Association House of Delegates and Board Member of the Society for Cardiac Robotic Navigation. He has been a faculty speaker and moderator at the Heart Rhythm Society, American College of Cardiology and Asia Pacific Heart Rhythm Society scientific sessions. He is a Fellow of the Heart Rhythm Society and Fellow of the American College of Cardiology.

Dr. Cheung has regularly been named a New York Magazine Top Doctor in Cardiac Electrophysiology since 2018. His other honors include: Castle Connolly Top Doctor in Cardiac Electrophysiology since 2015, 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 was a 2011 Weill Cornell Medical College Department of Medicine Investigators Research Award Finalist. He is fluent in Cantonese and Mandarin.
