doctor places an implantable cardioverter-defibrillator (also called an ICD) in
the chest. The ICD has one or two wires called leads that connect to the heart
through a vein. The ICD checks the heartbeat for an abnormal rhythm. If the ICD
senses an abnormal heart rhythm, it sends out either electrical pulses or a
shock to fix it.
