Mechanisms of electrical defibrillation of the heart.
This paper discusses the development of theoretical models of heart defibrillation by a bipolar impulse. These are based on theoretical mechanisms as well as our results obtained in a series of fibrillation/defibrillation experiments carried out in anesthetized mongrel dogs. The procedures for fibrillation and defibrillation have been previously described. During the experiments, blood pressure, ECG, and ventricular wall contraction strength are continuously recorded. The methods of recording have been previously described.
