On the basis of the model of the current flow through a single fibre, changes in the electric charge density over the myocardium are described. With the use of relevant analytic formulae, supported with numerical calculations, the distribution and time dependencies of electric potentials on the surface of the thorax have been determined. The results obtained are compared with empirical data. A strong correlation between the theoretical predictions and the experimental data has been obtained. The model in question permits examination of instantaneous potentials resulting from electrical activation of particular segments of the cardiac muscle.
