Dr. Sapp is Assistant Dean of Clinical Research and Professor of Medicine at Dalhousie University where he is also cross-appointed to the Department of Physiology and Biophysics within the Faculty of Medicine. Clinical and research interests include methods for improving cardiac mapping, catheter ablation, and clinical management of ventricular tachycardia.

Dr. John Sapp’s research efforts have centered primarily on ventricular tachycardia investigation and management. His research work includes studies of intramyocardial needle ablation for treatment-refractory ventricular tachycardia, the role of catheter ablation for ischemic ventricular tachycardia, and body surface mapping to derive an inverse solution and quantify its accuracy and the improvement of rapid mapping of ventricular tachycardia. Dr. Sapp was interim division head/chief of the Division of Cardiology from December 2016 to September 2017.
