title: [Microelectrode study of spontaneous defibrillation of the heart ventricles].
abstract: The authors investigated the cellular activity of the intact heart of guinea pigs of different age and pigeons both under normal conditions and during fibrillation. It is shown that spontaneous defibrillation is possible with high efficacy of cellular interaction. This leads to synchronization of the cellular activity, hyperpolarization of the cellular membrane and to the restoration of the normal rhythm. Increase of parasympathetic influence tends to block the mechanism of spontaneous defibrillation.
