Medical News Today -- The electrophysiology team at the Montreal Heart Institute (MHI) recently performed the first implantation of a new type of cardiac pacemaker (Accent RF™) in Canada. This landmark procedure was carried out on October 22, 2009 by Drs. Bernard Thibault and Peter Guerra. Both are cardiologists, electrophysiologists at the MHI and professors at the Université de Montréal. The Accent RF™ pacemaker uses wireless technology and is intended for people with bradycardia, an abnormally slow heart rate. The patient responded favourably to the procedure, and four additional implantations have since been performed, again with successful outcomes.
