Pacemakers:  NYU Langone Medical Center's Cardiac Electrophysiology / Heart Rhythm Center offers pacemakers for patients whose hearts are beating too slowly. These devices are used to take over the role of the heart's natural pacemaker -- the sinus node or the atrioventricular node -- when either fails to function correctly.

Defibrillators:  At the Cardiac Electrophysiology / Heart Rhythm Center we offer implantable cardioverter defibrillators (ICDs) for patients with life-threatening ventricular tachycardia or fibrillation. These devices are generally 99 percent effective in halting arrhythmias.
