Abstract
An apparatus for administering electrotherapy, such as a pacemaker, having an alarm system including a relatively small alarm electrode affixed to the external surface of a non-conductive portion of the case of the apparatus, such as the neck. The apparatus, is implanted with the alarm electrode in contact with a muscle. A switch permits the alarm electrode to be used as the indifferent electrode for providing a patient alarm. The amplitude of the output may be varied to provide different alarm levels; i.e. different twitching intensity of the muscle, to permit the patient and physician to distinguish between alarms of diagnostic interest and those indicating a hazardous or emergency condition.
