Abstract
A transthoracic electrical defibrillation method and apparatus for effectively defibrillating a fibrillating heart by delivering successive low energy electrical shocks to the fibrillating heart with the second such shock being applied at the onset of reinitiate fibrillation. Such low energy shocks produce current densities of sufficient magnitude to simultaneously place only a portion of myocardial cells in a refractory state, that portion being less than that necessary to defibrillate the heart. The composite effect of two or more low energy shocks each applied synchronously with the initiation or reinitiation of fibrillation, results in the successful defibrillation of a fibrillating heart.
