Mechano-mathematical model of excitation-contraction coupling in muscle tissue.

Abstract

A system of equations, describing the excitation-contraction coupling in cardiac muscle is obtained on the basis of a physiological model and of a thermodynamical one of a system with external control, the latter model being proposed by the authors. A single isometric contraction is modelled for latent, activation and relaxation periods. The obtained theoretical results coincide qualitatively with the experimental data.
