title: [Modeling atrial and ventricular contractility of the heart muscle. I. Modeling single contractions].
abstract: A system of differential equations describing myocardium contractions in isometric and isotonic regimes has been obtained. On the basis of these equations functioning of myocardium was modelled on an electronic computer. An effect has been revealed of the coefficients of rheological equations and activation function on isometric and isotonic contraction of the force/rate ratio. A good agreement between the results of modelling and the experimental data has been observed.
