Patient Age Group


Dr. Barrett received his BMedSc, MB BCh BAO degrees from the National University of Ireland, Cork. He completed his surgical and medical internships, and subsequently completed his internal medicine residency in Cork University Hospital. His cardiology fellowship training in Ireland was supervised and overseen by the Royal College of Physicians, Ireland. He then completed two years of fellowship training in Cardiac Electrophysiology at Cleveland Clinic, Ohio. Dr. Barrett joined the staff of the Cardiac Arrhythmia Service at Massachusetts General Hospital in 2008.

His main clinical and research interests focus on catheter ablation of cardiac arrhythmias, particularly ventricular tachycardia (VT), atrial fibrillation (AF), and other supraventricular tachycardias (SVTs). Dr Barrett also performs implantation and follow-up of cardiac devices therapy including pacemakers, Implantable Cardioverter Defibrillators (ICDs) and Cardiac Resynchronization Therapy (CRT) devices. He also performs LASER assisted extractions of implanted cardiac devices.

Dr. Barrett is currently accepting new patients.

Research & Publications

Research Summary

Dr Barret's research interests are in both the clinical and experimental (pre-clinical) fields.

He is currently engaged in collaboration with researchers in MIT on a project for enhanced mapping of ventricular arrhythmias. He also has collaborated with other researchers in Massachusetts General Hospital on projects involving localization and characterization of the scar involved in ventricular tachycardia, which can lead to sudden death. He also has been researched the feasibility of a novel pacing strategy for heart failure. Other research interests include novel and emerging technologies for catheter and balloon-based ablation. Dr Barrett is also an investigator for many multi-center studies involving ablation technologies and strategies, and also novel device technologies.
