Implantable cardioverter-defibrillator (ICD)

 Location of implantable cardioverter-defibrillator and connection to heart chambers

A doctor places an implantable cardioverter-defibrillator (also called an ICD) in the chest. The ICD has one or two wires called leads. Most of the time, these leads go into the heart through the subclavian 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.
