Pronunciation
Definition 1
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. (NCI Dictionary)
Definition 2
A battery-powered electrical impulse generator implanted in patients at risk of sudden cardiac death to detect cardiac arrhythmia and correct it by delivering a jolt of electricity. (NCI Thesaurus/CDISC)
