MSH: Implantable devices which continuously monitor the electrical activity of the heart and automatically detect and terminate ventricular tachycardia (TACHYCARDIA, VENTRICULAR) and VENTRICULAR FIBRILLATION. They consist of an impulse generator, batteries, and electrodes.,UMD: Implantable defibrillators that can also sense and provide corrective action for ventricular tachycardia and ventricular fibrillation by applying low-level synchronized electrical countershocks (cardioversion). Some of these stimulators have memory modules for storage and retrieval of the cardiac electrical activity and programmable capabilities.,UMD: Defibrillators that are permanently inserted (implanted) either abdominally or pectorally and are connected to the patient's heart through a set of epicardial or transversal leads. These defibrillators consist of a hermetically sealed container, including a lightweight battery, electronic circuitry to sense cardiac activity and produce the electrical pulses (shocks), and electrode leads t
