Transthoracic ventricular defibrillation in the dog with unidirectional rectangular double pulses

Abstract

The energy requirement for transthoracic ventricular defibrillation with unidirectional rectangular double pulse shocks was evaluated by means of 4,560 fibrillation-defibrillation episodes in dogs. The results obtained compare unfavourably with those previously observed with single pulse defibrillatory shocks.
