1. An automated external defibrillator, comprising:

  • a pair of defibrillator electrodes having a stored disposition and an operating disposition, the electrodes being disposed in an electrically conductive relationship in said stored disposition;

    a case including an electrode compartment and an openable lid for enclosing the compartment, the compartment configured to hold the pair of defibrillator electrodes;

    a lid switch for sensing when the lid is opened;

    electrode terminals in the electrode compartment, the electrode terminals configured for electrical interconnection to the defibrillator electrodes;

    a battery compartment and battery terminals in the case, the battery compartment and terminals and configured for holding and electrical interconnection to one or more batteries;

    a high voltage circuit coupled to the battery terminals and the electrode terminals, for generating defibrillation pulses and applying the pulses to the electrode terminals;

    an operator-actuated rescue switch on the case;

    a rescue indicator on the case; and

    a digital control system coupled to the lid switch, electrode terminals, high voltage circuit, rescue switch and rescue indicator, including;

    rescue mode initiating means for initiating rescue operation of the defibrillator when the lid is opened;

    rhythm analyzing means for analyzing signals present on the electrode terminals to identify a shockable cardiac rhythm;

    rescue indicator actuating means for activating the rescue indicator when a shockable rhythm is identified; and

    pulse initiating means for actuating the high voltage circuit and causing the generation of defibrillation pulses when a shockable rhythm is identified and the rescue switch is actuated;

    resume indicator actuating means for actuating the resume indicator if rescue data is stored in the digital control system when the lid is opened; and

    memory clearing means for clearing the rescue data from the digital control system when the resume button is actuated.
