Electrophysiology is the study of the heart’s electrical system – a cardiac specialty that provides crucial services to people with abnormal heart rhythms or arrhythmia.

Through Cape Cod Healthcare’s Heart and Vascular Institute, you have access to highly skilled cardiologists who specialize in electrophysiology (EP) and are trained in the latest advances for diagnosing and treating heart arrhythmias, such as atrial fibrillation.

Advanced Care for Heart Arrhythmia

When your heart beats too fast, too slow or irregularly, you need specialized cardiac care. Our electrophysiologists work closely with our cardiac surgeons, interventional cardiologists and other members of the cardiac team to determine the best treatment for your specific condition.

Diagnostic Methods

  • Diagnostic electrophysiology studies that involve threading a catheter into your heart to test its electrical impulses.
  • Patient-activated event recorder that is implanted under your skin and captures data about suspected arrhythmias.

Treatment Methods

  • Ablation - a minimally invasive catheter-based procedure to disable the abnormal heart tissue that causes arrhythmias. Electrophysiologists use two types of ablation, depending on the kind of arrhythmia and where the heart current is misfiring:
    • Radiofrequency ablation (burning)
    • Cryoablation (freezing)
  • Artificial pacemakers, including the Micra® Transcatheter Pacing System – the smallest minimally invasive pacemaker available.
  • Implantable cardiac defibrillator (ICD), a device placed under the skin that can control the heart’s rhythm and electrical impulses.
  • Watchman™ left atrial appendage closure – allows some arrhythmia patients to give up blood thinners without increasing their risk of stroke.

Other procedures that may be used alone or in combination with these treatments include:

  • Cardioversion can restore your hearts rhythm either through medication or an electrical shock to the heart while you are sedated.
  • Maze surgical procedure
  • Medication
