Main Page Content

​​​Image of heart diagramElectrical disorders of the heart or heart rhythm disorders are a major and increasing cause of sudden cardiac death and disability in both young and aging populations. Electrical disorders can manifest across a wide spectrum of arrhythmias (irregular heartbeats) from tachycardia (abnormal acceleration of the heart) and atrial fibrillation (irregular rapid heart rhythm causing the atria to quiver, or fibrillate) to bradycardia (sudden slowing of the heart) and ventricular fibrillation (irregular electrical activity causing the heart chambers to be unsynchronized thus pumping little or no blood).

The PMCC is an international leader in the investigation and treatment of heart rhythm disorders. Our specialists have already been able to contribute to breakthroughs that have impacted treatments, diagnosis and care of patients with electric disorders of the heart across Canada and around the world.​​​
