1. A method for forcing cardiac output during tachyarrhythmia in a patient, comprising the steps of:

  • (a) attaching a plurality of electrodes to external portions of a patient'"'"'s body proximate the patient'"'"'s thoracic region so that the electrodes may deliver electrical pulses which will be transmitted through portions of the patient'"'"'s upper body;

    (b) providing means for detecting the presence of tachyarrhythmia in the patient;

    (c) detecting the presence of tachyarrhythmia in the patient; and

    (d) delivering electrical current pulses through the patient'"'"'s body, via said electrodes after detecting tachyarrhythmia, at a rate between about 60 and 200 pulses per minute, said electrical current pulses having a voltage less than a normal defibrillation voltage level, to force contraction in the patient'"'"'s heart and facilitate a minimum level of cardiac output until cessation of the tachyarrhythmia or until other medical intervention is provided.
