<p>A two-channel defibrillator (10) has a programmable stimulator (44) to provide a means for assessing lethal ventricular tachyarrhythmias and determining defibrillation thresholds during implantable defibrillator procedures. To aid doctors and improve patient care at substantially decreased patient risk, the apparatus includes an automatic charging circuit, and dual channel high voltage capacitor circuits (34, 36) to reduce the time in which a rescue shock can be delivered to a patient after an initial test defibrillation shock. Parameter storage is provided to allow the apparatus to be preprogrammed prior to the initiation of an electrophysiologic procedure. A microprocessor (20) controlled display system provides the physician with information parameters regarding defibrillation shocks, including the energy delivered and the resistance in the patient. The apparatus also displays information regarding energy which is expected to be delivered based on the parameters entered.</p> |
