Abstract
A multiprogrammable, telemetric, implantable defibrillator contains a high energy shock system to revert VT/VF's to normal sinus rhythm and a multi-programmable VVI bradycardia support system. When the apparatus is in an automatic shock sequence, there are two points of reconfirmation: at the programmed minimum time to shock and after the full charge has been reached, or at thirty seconds, whichever comes first. Reconfirmation involves testing the tachycardia detection output (TDO). If the TDO is high, reconfirmation occurs. If the TDO is low, reconfirmation will not occur and the device will subsequently dump the discharge. Two reconfirmations must occur before a shock is delivered to the patient. If the TDO is low at either reconfirmation, the charge will be dumped.
