- (im-PLAN-tuh-bul KAR-dee-oh-VER-ter-dee-FIH-brih-LAY-ter) A small device used to correct a heartbeat that is abnormal (too fast, too slow, or irregular). The device is placed by surgery in the chest or abdomen. Wires are passed through a vein to connect the device to the heart. When it detects abnormal heartbeats, it sends an electrical shock to the heart to restore the heartbeat to normal. Also called ICD.
