Vision Statement


Andrew Krahn








Research Interests

My clinical expertise is in management of cardiac arrhythmias. Current research interests include investigation of genetic causes of arrhythmias, causes of loss of consciousness and implantable arrhythmia device monitoring. I am affiliated with several professional associations including the American Heart Association Council on Cardiology, the Royal College of Physicians of Canada, the American College of Cardiology, the Canadian Cardiovascular Society and the Heart Rhythm Society (Present from 2009 – 2011).
