ABSTRACT:
An automatic capacitor maintenance system for an implantable cardioverter defibrillator (ICD) reforms the capacitor system of the ICD based on measurements relating a current leakage and a charge time of the capacitor system as determined at a stable low voltage state. Preferably, differential changes in current leakage across the capacitor system are monitored and the capacitor system is reformed based on a pre-set estimated charge time. The automatic capacitor maintenance system produces significant savings in the amount of battery energy consumed to reform the capacitor system of an ICD, while maintaining the capacitor system at an optimum charging efficiency so as to insure high reliability of both the capacitor system and the ICD.
