Arrhythmia Services

The Harvard-Thorndike Electrophysiology Institute and Arrhythmia Service treats patients with the full range of conditions that cause abnormal heartbeats, from atrial fibrillation to ventricular tachycardia. Headed by Mark E. Josephson, MD, a pioneer of modern electrophysiology, it is the oldest, largest program of its kind in New England and provides care for patients from around the world.

A center of leading-edge research, advanced medical education and clinical care, the Institute offers the most advanced diagnosis and treatment modalities, including catheter-based ablation and cardioverter-defibrillator implantation.
