Dr. Jeanne Morrison, PhD
Family Practitioner

An implantable cardioverter-defibrillator (ICD) is a device used to monitor heartbeat and heart rhythm. It is placed under the skin and attached to the heart through the veins with small wires. The device emits an electrical pulse if the heart beats with a dangerous rhythm or if the heart stops. The electrical pulse shocks the heart back to a normal rhythm.
