Abstract

The bioelectrical sources of the heart are distributed through the space of the myocardium or, in an approximate consideration of the depolarization process, over the surface of the excitation wave front. Thus, it is sometimes advantageous to use models or other equivalent generators of a distributed type for mathematical description of the cardiac electrical generator. They should be preferred in comparison with idealized point generators, the formulation and interpretation of which meets with known difficulties. So attention was recently paid to the theoretical possibility of representing the cardiac generator by current sources in the form of a double layer over a closed surface surrounding the heart (Geselowitz, 1976).
