Dr. Nanthakumar has been a Cardiologist and Cardiac Electrophysiologist at Toronto General Hospital for 20 years, where he has served as Director of Heart Rhythm Disorders for a decade. He became a full Professor of Medicine at the University of Toronto (U of T) in 2014 and is also a Senior Scientist at Toronto General Hospital Research Institute. He is a dedicated teacher, passionate in training and mentoring future electrophysiologists in complex electrophysiological interventions both locally and internationally. He holds global acclaim in intracardiac mapping with DeEP, Omnipolar, and Repolarisation mapping among his fields of expertise. He has a prolific publication record of over 200 original peer-reviewed journal articles and has been cited over 5,900 times with an h-index over 40. He is also an inventor/innovator at Techna.

The majority of Dr. Nanthakumar's medical education and training took place at U of T, starting in 1991. He completed medical school at U of T in 1995, followed by postgraduate training in Internal Medicine and Cardiology also at U of T. He subsequently completed an additional 3-year subspecialization in cardiac electrophysiology at the University of Alabama in Birmingham, USA, where he studied the mechanisms of cardiac arrhythmias and built expertise in cardiac mapping. His clinical expertise is focused on devices for heart failure and performing catheter ablation of ventricular tachycardia and supra ventricular tachycardias.
