A Numerical and Experimental Investigation of the Degree of Chaos of the Activity of the Simulation Environment in Ventricular Fibrillation with the Functioning of Various Numbers of Ectopic Foci

Abstract

The relationship between the degree of chaos of the activity of the simulation environment in ventricular fibrillation and the number of ectopic foci has been studied. The degree of chaos of the activity of the simulation environment was estimated by entropy and phase portraits of the amplitudes of fibrillary oscillations. The results of computational experiments were compared with the results of physiological experiments performed on rats and dogs. The study has shown that the degree of chaos of the activity of the simulation environment increases with the growth of the number of ectopic foci in the ventricular myocardium.
