Patent ID: 8805491

Claim:
A method of treating a patient in cardiac arrest (including in fibrillation, electrochemical dissociation, or asystole), the method comprising: delivering an agent for enhancement of cardiac function to the patient's coronary arteries, wherein delivering the agent comprises intravenous infusion of the agent and a circulatory enhancement method for delivery of the agent to the coronary arteries; and microperfusing the patient's cardiac tissue by electromagnetically stimulating the cardiac tissue with a plurality of microperfusing pulses, applied via electrodes external to the patient, wherein the microperfusing pulses are at an energy below a threshold sufficient to defibrillate the patient's heart and below a threshold sufficient to pace the patient's heart with hemodynamic output, but of a frequency, duration, and energy level to produce sufficient myocardial cell contraction for pumping of Calcium ions into the cell interior without causing electroporation of the myocardial cells.
