Implantable Cardioverter Defibrillator

For arrhythmias in which the heart beats too rapidly (tachycardia) or quivers (fibrillates) instead of contracting strongly, an internal cardioverter defibrillator (ICD) can be surgically implanted.

The ICD sends electronic signals to the heart whenever the heart rate reaches a specified limit or goes very high. These signals shock the heart into beating more slowly and pumping more effectively. An ICD is generally not used to treat atrial fibrillation.
