Cardiac Defibrillation Implantation

An implantable cardioverter defibrillator (ICD) is a device that is placed permanently inside your body. An ICD monitors your heart rhythm (the speed and pattern of your heartbeat). If this rhythm becomes too fast or too slow, the ICD sends out electrical signals that help bring the rhythm back to normal. The ICD is put inside your body during a minor surgical procedure called implantation. In most cases, implantation takes 1 to 3 hours.
