Implantable cardioverter-defibrillators (ICDs) (10) are disclosed that are entirely implantable subcutaneously with minimal surgical intrusion into the body of the patient and provide distributed cardioversion/defibrillation (13 , 23) and pace/sense (22, 24, 26, 28) electrodes for delivery of cardioversion/defibrillation shock and pacing therapies across the heart (10 2) when necessary. At least two hermetically sealed housings (11, 21) forming first and second hermetically sealed housings coupled together by a cable (3 0) support first (13), second (23) and, optionally, third (32) cardioversion/defibrillation electrodes. The relatively bulky high voltage battery (12) and high voltage capacitors (56, 58, 60, 62), and circuitry powered by a low voltage power source (53) for detecting a tachyarrhythmia, changing the high voltage capacitor, and discharging the high voltage capacitor to provide a cardioversion/defibrillation shock are distributed between the first (11) and second (21) hermetically sealed housings.
