This allows the doctor to detect any changes in your condition, such as shortness of breath, even before you notice symptoms. Implantable cardioverter defibrillators detect a life-threatening, rapid heartbeat called ventricular fibrillation and deliver a series of electrical pulses or an electrical shock, restoring the normal heart rhythm.
Cardiac Resynchronization Therapy (CRT)
This is known as defibrillation. People with dilated cardiomyopathy are often candidates for implantable defibrillators, as are some people with hypertrophic cardiomyopathy. At NYU Langone, cardioverter defibrillators are implanted through an incision under the collarbone. The procedure takes 30 to 60 minutes and requires an overnight stay in the hospital. For two weeks after the procedure, your activities may be restricted, including driving and lifting items heavier than 10 pounds. A pacemaker—a battery-operated device the size of two half-dollar pieces pressed together—is implanted in the chest to keep the heart beating at a normal rate.

The device sends electrical signals to your heart to help it maintain a regular rhythm. Biventricular pacemakers are typically used to manage arrhythmias, or irregular heartbeats, caused by heart failure. The type of device works like a conventional pacemaker, which is connected to the heart with two or more wires, called leads. NYU Langone heart surgeons typically implant the pacemaker under the skin, below the right or left collarbone.
Pacemaker implantation is performed using a sedative as well as a local anesthetic at the implantation site.

Despite significant advancements in the treatment of heart failure over the past 2 decades, this patient population is still subject to considerably high morbidity and mortality rates. In recent years, the field of device therapy as adjunctive treatment to the medical management of congestive heart failure has grown in the wake of the large number of randomized trials that have demonstrated the safety and efficacy of these devices.
The implantable defibrillator currently represents the standard of care in certain segments of the heart failure population, even in those without a prior arrhythmic event.

Biventricular pacing systems appear to have a role in heart failure patients with prolongation of their QRS duration in improving ventricular performance and symptoms, if not mortality. Last, the shortage of organs available for orthotopic transplant has heightened interest in using ventricular-assist devices as destination therapy, and although there is evidence for the feasibility for this approach at the current time, there is a next generation of devices that appear even more promising.
