A Two Dimensional Bond Graph Model Of A Sarcomer

Abstract

This work concerns a Bond Graph modelling of the cardiac muscle cells named sarcomer. The dynamic behaviour of a set of connected sarcomers are analysed according to two directions. Some hypotheses are made to model the elements that cause the variations of a flat section taken in an auricle or a ventricle cavity of the heart. We assume that these dimensional variation result from the sarcomer dynamics. Bond Graphs models representing forces and motions of an isolated sarcomer are presented, followed by a Global one and its corresponding state space equation. To model this particular system, we take into account some of its electric, hydraulic, and mechanical multi field characteristic.
