Electrophysiology is a branch of cardiology which helps doctors to evaluate the heart’s electrical activity and understand and locate abnormal heart rhythms. In the Heart and Vascular Centre we often use an electrophysiology study to evaluate patients who have “fainted” or have experienced an abnormal rapid heart rhythm. We also recommend this for patients who have impaired heart function and intermittent extra heartbeats. In some situations, our patients with a congenital cardiac condition may need an electrophysiology study in order to assess their risk of developing serious arrhythmia.

Based on electrophysiology study results, our consultant electrophysiologist decides on the treatment, medication, catheter ablation, implantation of a pacemaker or defibrillator to manage the heart’s rhythms, or more diagnostic tests.

The following are some of the services which are provided in the electrophysiology clinic:

  • Outpatient and inpatient consultation service
  • Invasive and non-invasive investigations for heart rhythm disorders other than electrocardiography, such as Holter monitoring (portable device) and extended cardiac rhythm monitors
  • Invasive electrophysiological procedures when required to diagnose arrhythmias and conduction disturbances and catheter ablation of these arrhythmias when appropriate
  • Assessment of patients with syncope (fainting) to exclude life threatening arrhythmias and genetic syndromes
  • Assessment and management of patients who require implanted cardiac rhythm devices
  • Follow up of patients with cardiac pacemakers, defibrillators or implanted loop recorders
