ABSTRACT:
A method and apparatus for performing electrophysiologic testing on a patient's heart using an implantable pulse generator system. The system includes an implantable pulse generator such as an implantable cardioverter-defibrillator having high voltage capacitors for storing electrical energy to defibrillate the patient's heart, a means for inducing a cardiac arrhythmia, an electrode system for discharging the stored energy into the patient's heart, and an external programmer for communication with and command of the implantable pulse generator. The method comprises the steps of charging the capacitors to a selected energy level upon command from the external programmer, inducing fibrillation in the patient's heart following the charging step, and discharging the capacitors through the electrodes into the patient's heart to defibrillate the patient's heart. The method and system provides flexibility in electrophysiologic testing by allowing the physician to control the time of delivery of high voltage therapy.
