we present a model to be displayed on a medium scale analog computer , which describes excitation-contraction ( e-c ) coupling of the mammalian myocardium in terms of calcium movements occurring , on a sarcomere level , in a multicompartment system , despite the fact that its mathematical formulations are oversimplifications of the mechanism involved , because the number of differential equations had to be limited , the model predicts with fair accuracy a large variety of inotropic phenomena thought to be the result of factors influencing cardiac e-c coupling in one way or another .
