Nair, Girish

Overview 

Dr. Girish Nair is an electrophysiologist and director of the cardiac electrophysiology and arrhythmia service in the Division of Cardiology at the University of Ottawa Heart Institute, and a full professor in the Department of Medicine at the University of Ottawa. He is also cross-appointed from the Department of Medicine to the School of Epidemiology and Public Health, University of Ottawa.

Background 

Dr. Nair graduated from the Jawaharlal Nehru Institute of Post Graduate Medical Education and Research (JIPMER), a deemed University in Pondicherry, India. He completed his residency in internal medicine and cardiology from the University of Delhi. He moved to Canada in 2002 and completed a clinical/research fellowship in interventional cardiac electrophysiology from the University of Toronto and associated Toronto General Hospital. Dr. Nair has also completed his MSc in health research methodology from McMaster University.  He served as a faculty in the Division of Cardiology at McMaster University from 2004 to 2012. Dr. Nair joined the Division of Cardiology at the University of Ottawa Heart Institute in October 2012 and is currently a full professor of medicine.

Research & Clinical Interests 

Dr. Nair is a clinician-researcher with the Ottawa Heart Institute Research Corporation (OHIRC), and his current research interests include quantitative research methods for atrial fibrillation, sudden cardiac death and ventricular tachycardia with a specific focus on evaluating treatment strategies and knowledge transfer. He currently holds peer-reviewed grants from multiple sources (CIHR, HSFC) and is leading clinical trials evaluating treatment strategies for atrial fibrillation and other cardiac arrhythmias. He has cross-appointment from the Department of Medicine to the School of Epidemiology and Public Health, University of Ottawa, with supervisory privileges (co-supervision, MSc And PhD).

Dr. Nair’s clinical focus is on complex ablations including atrial fibrillation, ventricular tachycardia and arrhythmias in the adult congenital heart disease population.
