Implantable cardioverter-defibrillator - Definition

Ask a question


An implantable cardioverter-defibrillator (ICD) is a medical device for cardiac stimulation, intended to treat certain cardiac pathologies. Positioned in cardiac cavities, the probes of the defibrillator permanently analyze the heart rate and stimulate the muscle if necessary. This type of machine may have one or several probes. A single-chamber defibrillator has only one probe, a double chamber has two, and a triple chamber has three. The ICD mainly anticipates the risk of a recurring cardiac complication.
