James Ip, M.D.
"I have been fortunate to have been trained and mentored by some of the country's finest physicians. It is a great honor for me to care for patients through the practice of electrophysiology. I am committed to clinical excellence, teaching and research for the betterment of my patients and the advancement of academic medicine."
James Ip, MD, FACC, FHRS was born and raised in New York City. After graduating summa cum laude from Columbia University, he attended Harvard Medical School. There, he received a Doris Duke Clinical Research Fellowship, which enabled him to pursue research in cardiovascular genetics and stem cell therapy. He completed his internal medicine residency at the Brigham and Women's Hospital in Boston and returned to New York for his cardiovascular disease and cardiac electrophysiology fellowships at Cornell University Medical Center.
While at New York Presbyterian Hospital, Dr. Ip has performed thousands of procedures, including catheter ablations of arrhythmias and implantation of cardiac devices (such as pacemakers, defibrillators and biventricular devices), including the recently developed subcutaneous defibrillator.
With over thirty peer-reviewed journal publications, Dr. Ip has authored numerous articles in the field of cardiac electrophysiology involving cardiac device diagnostics, catheter ablation techniques and mechanisms of arrhythmias. He is the principal investigator at Cornell for the multicenter trial to evaluate the safety and effectiveness of the first leadless cardiac pacemaker system. Dr. Ip also maintains an active research focus on developing an animal model of ventricular tachycardia to elucidate the molecular mechanisms of certain types of arrhythmias.
Dr. Ip teaches medical students, residents and fellows at Cornell.
