Arrhythmia Management

Arrhythmia Management

Arrhythmia is caused by electrical short circuits in the heart that cause it to beat irregularly — too fast or too slowly.

Thankfully, arrhythmias can be treated and even cured by specialized cardiologists, called electrophysiologists. In fact, our arrhythmia management program is led by the only four electrophysiologists in the whole Central East LHIN region.

Services and Procedures

Pacemaker and ICD implants

If you have a serious arrhythmia condition, a pacemaker or implantable cardioverter defibrillator (ICD) may be needed. These devices are implanted in your chest or abdomen, which is a minor surgical procedure performed by our arrhythmia team.

Who’s it for?

An pacemaker or ICD may be recommended for people who:

  • Have brady-arrythmias (slow heart rhythms)
  • Have syncope (unexplained fainting spells), heart failure and hypertrophic cardiomyopathy
  • Have had a prior episode of sudden cardiac arrest
  • Have had a prior episode of ventricular fibrillation
  • Have had at least one episode of ventricular tachycardia
  • Have had a prior heart attack and have an increased risk for sudden cardiac arrest or sudden cardiac death

Ongoing follow-up care

After having a pacemaker or ICD implant, we provide you with ongoing follow-up care. This includes education and monitoring of your device and condition.

Electrophysiology & ablation

We perform electrophysiology studies to identify which areas of the heart are causing your arrhythmia, then correct the arrhythmia through a catheter ablation. In this procedure, we cauterize or burn the heart cells that are causing the abnormal heart beat. We perform simple and complex ablations to treat atrial flutter, atrial fibrilation, as well as ventricular tachycardia.

Who’s it for?

An EP study or an ablation is required for people who:

  • Have AV nodal reentrant tachycardia (AVNRT), an extra electrical pathway in their AV node that causes impulses to go back to areas they already passed through
  • Have atrial fibrillation (rapid beating of the atria) or atrial flutter (quivering of the atria)
  • Have ventricular tachycardia, a rapid and life-threatening heart rhythm caused by impulses in the ventricles

Accessing Services

If you are in need of arrhythmia services, your physician may send a referral to our regional cardiac centre, which can be faxed to 416-281-7470.
