1. A physiological electrode system for use in conveying electrical signals to and from between the human body and certain electrical devices comprising:

  • a first non-invasive electrode element to be attached to the skin of a patient;

    a second non-invasive electrode element to be attached to the skin of the patient, said first and second electrode elements capable of producing desired operation of each of a monitoring device, a stimulating device and a therapeutic device;

    interrelating means for selectively separately connecting said electrode elements to a monitoring device, a stimulating device or a therapeutic device to produce desired operation of each such device through said electrode elements, the monitoring device, the stimulating device and the therapeutic device being otherwise separate and unrelated, said interrelating means providing for the simultaneous connection of said electrode elements to at least two of said devices; and

    protective means associated with said interrelating means for selectively permitting desired combinations of the monitoring device, the stimulating device and the therapeutic device to be simultaneously connected to the patient solely through said first and second electrode elements.
