Volume of electrophysiology activities

The Electrophysiology Department has one laboratory occupying two rooms. The MHI was the first centre in Canada in 1999 to use an endocavitary mapping system.

This sophisticated system makes it possible to precisely locate within a few millimetres the site of origin of arrhythmias such as auricular tachycardia, auricular flutter, auricular fibrillation and ventricular tachycardia.

The Department also operates two specialized clinics: the Pacemakers-Defibrillators Clinic, where patients with either device attend for follow-up; and the Arrhythmia Clinic, where patients attend either for a new consultation or for follow-up of complex arrhythmic problems.

In 2002-2003, out of a total of 1,604 interventions, 591 related to permanent pacemakers; 325 consisted of electrophysiological studies; 298 involved catheter ablation of arrhythmias; 249 related to defibrillators, and 141 interventions fell under separate categories.
