Abstract
A power supply for an implantable cardioverter-defibrillator for subcutaneous positioning between the third rib and the twelfth rib and using a lead system that does not directly contact a patient'"'"'s heart or reside in the intrathoracic blood vessels and far providing anti-bradycardia pacing energy to the heart, comprising a capacitor subsystem for storing the anti-bradycardia pacing energy for delivery to the patient'"'"'s heart; and a battery subsystem electrically coupled to the capacitor subsystem for providing the anti-bradycardia pacing energy to the capacitor subsystem.

3. A method of pacing a patient through a bradycardia event comprising:
-
providing a pair of stimulus electrodes exclusive of the patient'"'"'s heart; providing an implantable stimulus device at a subcutaneous location, the implantable stimulus device housing an energy source and an energy storage device and being coupled to a lead system including at least one electrode of the electrode pair; determining whether the patient has an abnormally slow heartbeat by sensing events in the patient'"'"'s cardiac rhythm; transferring energy from an energy source to an energy storage device; and discharging energy from the energy storage device using the stimulus electrodes;
wherein one of the stimulus electrodes is disposed on the implantable stimulus device. - View Dependent Claims (4, 5)
