Heart Rhythm Disorders Program

Heart rhythm disorders (arrhythmias) are disturbances in the normal rhythmic beating of the heart, causing it to beat too slowly or too fast. The most common type is atrial fibrillation. Although these abnormal rhythms sometimes occur in a healthy heart and have minimal consequences, they often indicate an underlying heart disease which can result in serious complications such as a stroke or heart attack. Learn more about heart rhythm disorders and atrial fibrillation.

The Heart Rhythm Disorders Program at the Brigham and Women’s Hospital (BWH) Heart & Vascular Center is known worldwide for its expertise in the evaluation and treatment of a range of abnormal heart rhythms affecting a variety of patients, particularly those with complex medical concerns.

Our board-certified cardiologists—renowned researchers in cardiac electrophysiology— serve on the faculty at Harvard Medical School. They lead a multidisciplinary team of nurses, physician assistants, technicians, fellows and research assistants in the exclusive care of patients with irregular heart rhythms, heart palpitations and rapid heartbeats.

Together, this specially trained team performs more than 3,000 procedures annually, including catheter ablationimplantable cardioverter defibrillator (ICD)pacemaker implantation and cardiac resynchronization. We are an international referral site for transvenous lead extraction.

As leaders in cardiac rhythm conditions, we train the next generation of physicians and surgeons through the Clinical Cardiac Electrophysiology Training Program.

The Heart Rhythm Disorders Program is actively involved in clinical trials and research, offering patients the opportunity of potential treatment options that are not available elsewhere.
