Patent Images
1. An implantable heart defibrillator comprising:
- means for administering defibrillation therapy to the heart of a patient by delivering defibrillation pulses in vivo to said heart via at least one defibrillation electrode; and
post-therapy means for delivering at least one stimulation pulse, after completion of said defibrillation therapy, to said heart via said defibrillation electrode, said stimulation pulse having energy significantly higher than a cardiac pacing pulse of approximately 0.04 millijoules and less than a defibrillation pulse of a range of 20-50 Joules.

Abstract
An implantable heart defibrillator is equipped with at least one intracardiac defibrillation electrode. A post-therapy apparatus is arranged to emit, after a defibrillation pulse, at least one stimulation pulse through the defibrillation electrode, the stimulation pulse having energy far higher than the energy in a normal heart stimulation pulse for cardiac pacing, but less energy than a normal defibrillation pulse.
