North Shore Medical Center (NSMC) provides the latest diagnostic and treatment options to manage irregular heart rhythm conditions, also known as arrhythmias. The full spectrum of arrhythmia care is offered, including head up tilt-table testing, comprehensive electrophysiology studies and implantable defibrillator and pacemaker implantation. The Pacemaker/ICD clinic team includes electro-physiologists, physician assistants, registered nurses, and a cardiac technologist and is the most comprehensive of its kind on the North Shore.

Finding her Rhythm

For more than a decade, Nicole Smith, 33, of Lynn suffered from what she thought were panic attacks. At least once a month, without any advance warning, her heart would race uncontrollably for short bursts of time—usually just a few minutes—leaving her a bit dizzy and lightheaded when it stopped. watch video

Cardiac Electrophysiology Program

Our cardiac electrophysiologists evaluate and treat the full range of rhythm disturbances including rapid and slow heart rates, palpitations (skipped or extra beats), lightheaded spells and blackout spells. They place and manage electronic pacemakers for slow heart rhythms and cardiac resynchronization therapy (CRT) pacemakers, also place and manage electronic implantable defibrillators. When necessary, they provide a full range of invasive electrophysiology testing and treatments, including ablation therapy, which can permanently cure some rapid rhythms.
