The effect of mechanical vibration on the diastolic performance of the left ventricle is simulated numerically on the basis of the model of Beyar and Sideman, in which the contraction mechanism of the myocardium is taken into consideration and the left ventricle is modelled by an ellipsoid of revolution. The model is improved by adding the effect of the reduction in the contractile force due to mechanical vibration and the effect of diastolic failure of the left ventricle. This simulation gives the same result as the experiment, in which the pressure during systolic period is increased and that during diastolic period is depressed markedly by the mechanical vibration only during the diastolic Period.
