1. Title:
A MODEL OF HEART ELECTRICAL DYNAMICS WITHIN THE FRAMEWORK OF KORTEWEG-DE VRIES AND SINE-GORDON EQUATIONS
Authors:
A.A. Berezin, K.A. Berezin.



Abstract:
In the model of heart electrical dynamics the fibrillation mode has been found to be decoupling of the solutions of the system of Korteweg de Vries and sine-Gordon equations and their transformation into intermittent solutions of the Korteweg de Vries or sine-Gordon equations. The results of the physical modeling of the electrical heart muscle dynamics agree with the solutions of the mathematical model and the actually observed modes of the heart work.
