Abstract
An implantable cardioverter defibrillator (ICD) device provides capacitor reformation by successively charging and leaking its output capacitor either a specified number of times or until a specified charge remains on the output capacitor after leakage. The ICD delivers therapy with minimal delay should an arrhythmia detection occur during the capacitor reformation process by anticipating an arrhythmia detection and dumping the reformation energy stored on the output capacitor to an acceptable level as soon as a possible arrhythmia detection is anticipated. The ICD further measures the energy level of the last charge delivered following each delivery so that the energy level of subsequent charges may be adjusted to provide optimal therapy to the patient if prior therapy attempts have not successfully terminated the arrhythmia.
