STIMULATOR FOR TREATMENT OF TACHYCARDIA WITH A BURST OF STIMULI HAVING A CONTINUOUSLY VARIABLE RATE

摘要

An externally activated implantable heart stimulator. Apparatus is disclosed for supplying to the heart of a patient a burst of stimulating pulses having a repetition rate in excess of the physiological heartbeat range of the patient. The stimulator comprises terminals for connection to the heart, a controllable electrical stimuli generator controlled internally by a discharging capacitor and controlled externally by a magnet. The stimulator is particularly applicable to the treatment of paroxysmal supra-ventricular tachycardias, a rapid heartbeat condition originating in the atrium. The stimulator can be temporarily activated by anyone including the patient being stimulated.
