1. A cardiac monitoring and external defibrillation system which allows an untrained human enabler immediate access to a medical professional who can and will remotely monitor, diagnose and treat a victim of medical emergency at one of a plurality of remote sites, said system comprising, in combination:

  • (a) a central station comprising;

    (1) a first display device for displaying cardiac information from a victim for evaluation by said medical professional;

    (2) a first input device, responsive to said medical professional, for producing control signals for controlling operation of emergency cardiac monitoring and external defibrillation apparatus at one of said remote sites and the application of a defibrillation pulse to said victim at said one site; and

    (3) a first transmitting/receiving (T/R) device, coupled to said first display device and said first input device, for electronic communication with emergency cardiac monitoring and defibrillation apparatus disposed at each of a plurality of remote sites; and

    (b) emergency cardiac monitoring and external defibrillation apparatus disposed at each of a plurality of remote sites, each said apparatus comprising a portable unit including;

    (1) a second transmitting/receiving (T/R) device for electronic communication with said first T/R device of said central station;

    (2) a master control unit, connected to said second T/R device, for controlling the operation of said cardiac monitoring and defibrillation apparatus, said control unit having a plurality of operating states selected from the group consisting of;

    (i) enable remote control by medical professional;

    (ii) enable automatic local control; and

    (iii) enable local control by emergency medical personnel;

    (3) a defibrillator circuit, having a control input coupled to said second T/R device and said master control unit, for generating a defibrillation pulse at a defibrillator circuit output in response to a defibrillation control signal received at said defibrillator circuit control input;

    (4) a logic device for automatic local control of the portable unit, coupled to said second T/R device, to said master control unit and to the control input of said defibrillator circuit, for automatically producing a second defibrillation control signal for controlling the application of said defibrillation pulse to said victim in response to electrocardiogram (ECG) signals received from said victim;

    (5) an electrocardiogram (ECG) circuit, having an ECG circuit output, coupled to said second T/R device and to said logic device, and having an ECG electrode input;

    (6) a plurality of contact electrodes, adapted to be placed by a nearby enabler upon a chest wall of said victim, said plurality of contact electrodes being adapted to be arranged at separate locations on said chest wall for the receipt of ECG signals from said victim and for application of said defibrillation pulse to said victim;

    (7) a connecting cable having a plurality of electric wires for connecting each of said contact electrodes to at least one of (i) said ECG electrode input and (ii) said defibrillator output;

    (8) a second display device, coupled to said ECG circuit output for display of said ECG signals; and

    (9) a second input device, coupled to said control input of said defibrillator circuit, for locally activating defibrillation;

    wherein(1) said ECG signals are transmitted from selected ones of said contact electrodes via said ECG circuit to said central station and displayed on said first display unit for evaluation by said medical professional, (2) said first defibrillation control signal may be transmitted from said central station to said control input of said defibrillator circuit and (3), in response thereto, said defibrillator circuit generates said defibrillation pulse for application to at least one of said contact electrodes for resuscitation of said victim; and

    wherein said master control unit selects the operating state of said portable unit at the remote site under control of said medical professional at said central station; and

    wherein, if enabled by said medical professional, (4) said ECG signals are transmitted from selected ones of said contact electrodes via said ECG circuit and displayed on said second display unit for evaluation by said emergency medical personnel, (5) said first defibrillation control signal may be transmitted from said second input device said control input of said defibrillator circuit, and (6), in response thereto, said defibrillator circuit generates said defibrillation pulse for application to at least one of said contact electrodes for resuscitation of said victim.
