Biography

Dr. Paul Dorian is the Department Director, Division of Cardiology, University of Toronto and Staff Cardiac Electrophysiologist at St. Michael’s Hospital. He is Professor of Medicine in the Division of Cardiology and in the Division of Clinical Pharmacology at the University of Toronto, and a Staff Scientist at the Li Ka Shing Knowledge Institute.

Dr. Dorian received his medical degree from McGill University in Montreal in 1976. He continued training in Internal Medicine and Cardiology at the University of Toronto, and received certification by the Royal College of Physicians and Surgeons of Canada in Internal Medicine in 1983 and certification in Cardiology in 1984. He completed training in Clinical Pharmacology at the University of Toronto in 1982, and received an MSc in Pharmacology from the University of Toronto in 1982. From 1983 to 1985, he completed a Fellowship in Cardiac Electrophysiology at Stanford University Medical Centre in California.

His research interests include basic science research in advanced cardiac life support and atrial fibrillation, the clinical pharmacology of antiarrhythmic drugs, and clinical research on implanted devices, antiarrhythmic drugs, and quality of life in patients with arrhythmias.

He is the immediate Past-President of the Canadian Heart Rhythm Society, Chairman of the Cardiac Arrest Committee, St. Michael’s Hospital, Co-Principle Investigator on the National Institutes of Health funded Resuscitation Outcomes Consortium, and serves on the steering committee of multiple multicenter clinical trials in arrhythmia care. He is the Chair of the Canadian Cardiovascular Society Quality Committee.

He has published over 350 peer reviewed papers and is Associate Editor of the textbook Electrophysiological Disorders of the Heart.

Please note: Dr. Dorian is not taking any summer students in 2018.
