Propagation of electric excitation and the appearance of auto-oscillations in an inhomogeneous myocardium

Abstract

Among the processes occurring in the cardiac tissue, the distribution of electrical excitation plays the leading role, since it determines and triggers all other processes in the myocardium. One of the dangerous cardiac disorders is the emergence of self-replicating wave processes that do not lead to contraction of the heart as a whole organ. Such processes may be caused by additional sources of electrical excitation, as well as by defects existing in the myocardium. The article presents the results of numerical simulation of electrodynamic processes in the myocardium, which makes it possible to analyze the myocardium
autoscillatory modes and identify the factors contributing to the appearance of these phenomena and, on the contrary, blocking their development.
