<p>Disclosed is a permanently implantable cardioverter, or defibrillator, including built-in interrogation and testing circuitry. Implanted fault detection circuits react to malfunctions in the implanted fibrillation detection circuitry, and ensure that inappropriate defibrillation pulses are not delivered to the wearer. Also disclosed is an implantable externally actuable interrogation and test circuit which interrogates the sensing circuitry for faults, and which delivers a realistic defibrillation pulse to an implanted test load. An external device for monitoring the operation of the implanted defibrillator is also disclosed.</p> |
