Pacemaker and Implantable Defibrillators


Pacemakers and implantable cardioverter defibrillators (ICDs) are used in patients with an arrhythmia. These small, battery-powered devices are implanted in the chest or abdomen.

A pacemaker helps control abnormal heart rhythms. It uses electrical pulses to prompt the heart to beat at a normal rate. An ICD monitors heart rhythms. If it senses dangerous rhythms, it delivers a shock called defibrillation. This can help control life-threatening arrhythmias. Most new ICDs can also act as a pacemaker.
