[Sympathetic control of spontaneous cardiac defibrillation].
The parameters of transmembrane potentials of cardiomyocytes and dynamics of fibrillation process have been investigated when altering the level of sympathetic action on the heart by injection of rausedile, katecholamines and by stimulation of the nucleus of hypothalamus. It was shown that the injection of rausedile decreases rest potential and potential activity, meanwhile electrical irritation significantly increases the period of spontaneously reversible fibrillation.
