Wilfred Bigelow and John Callaghan successfully paced the heart of a dog using an external electronic pacemaker-defibrillator having implanted electrodes.

The use of an Implantable atrioventricular synchronous pacemaker is described in the American Journal of Cardiology. This pacemaker derived from a combination of surgical and engineering developments following the Second World War. In 1949 Wilfred Bigelow, MD of the University of Toronto and his trainee, John C. Callaghan, MD, began developing hypothermia for use in reducing metabolism and producing bradycardia during which intracardiac procedures could be performed. In medicine, surgeons brought back many new techniques from the war; similarly, engineers and scientists in Canada witnessed rapid developments in radar and electronics. Wilfred Bigelow describes recovery from open heart surgery during hypothermia in dogs.

Former students are paying tribute to Dr. Wilfred Bigelow, father of open-heart surgery in Canada.

He theorized that cooling patients before they went in to surgery would lower the amount of oxygen circulation he needed and allow for a longer safer surgery.
