Abstract

A system and method for reducing the perceived pain by a patient occurring during cardioversion/defibrillation countershocks to the heart. The system comprises an electrode subsystem for positioning at least one electrode in contact with a patient, a pain reducing stimulation subsystem for providing pain reducing electromagnetic stimulation to the electrode subsystem, a cardioversion/defibrillation countershock subsystem for treatment of cardiac fibrillation, and a control subsystem. The control subsystem provides synchronization of the pain reducing stimulation subsystem with the cardioversion/defibrillation countershock subsystem so that delivery of pain reducing stimulation to the patient begins prior to a cardioversion/defibrillation countershock.
