1. A system for testing implantable cardioverter-defibrillators during implant, the system having an implantable cardioverter-defibrillator means for applying rescue cardioversion-defibrillation shocks to the heart of a patient in conjunction with implantation of the implantable cardioverter-defibrillator means, the system comprising:

  • first electrode means for implant in the heart;

    second electrode means for positioning adjacent said heart;

    the cardioverter-defibrillator means including;

    circuitry means connected to the first electrode means and the second electrode means, the circuitry means for applying cardioversion-defibrillation shocks to the heart between the first electrode means and the second electrode means for determining the defibrillation threshold of the heart during implantation of the implantable cardioverter-defibrillator means;

    removable external surrogate electrode means for temporary attachment to the skin of the patient and for detachable connection to the implantable cardioverter-defibrillator means in parallel with the second electrode means during implantation of the implantable cardioverter-defibrillator means; and

    switch means for electrically connecting the external surrogate electrode means to the implantable cardioverter-defibrillator means for applying a rescue shock from the implantable cardioverter-defibrillator means between the external surrogate electrode means attached to the skin of the patient and the first electrode means during implantation of the implantable cardioverter-defibrillator means wherein the external surrogate electrode means and the switch means include means for detaching the external surrogate electrode means and the switch means from the implantable cardioverter-defibrillator means.
