title: [New results in computer simulation of the spread of excitation in the myocardium].
abstract: The paper presents the results from three series of simulation experiments performed by means of a realistic computer model of activation propagation in the myocardium. Simulation of two types of hypertrophy showed that hypertrophy of the ventricles without their simultaneous dilatation leaves the parameters of the cardioelectric field virtually unchanged. Change in the activation rate in the layer of elements formed by the intraventricular surface of the cavities, compared to the rate in the other elements of the heart, considerably affects the magnitude and orientation of cardiac vectors during the middle and terminal phase of activation. Rotation of the model heart around its longitudinal axis induces similar changes in the time course of the cardiac vector as are observed in some types of hypertrophy and in volume load of the ventricles.
