The paper considers the possibility of assessing the relative intensity of the ion current flowing through the epicardial surface at different times of the building and restoration of the form of the action potential. On the basis of Maxwell's equations is obtained interconnection capacity at the epicardial surface and bulk density unipolar current sources. It is shown that the epicardial surface potential due to the distribution of bulk density unipolar sources and distribution of currents in the conductive medium, depending on the conductivity distribution in space. A model of the bulk density of the ion current to the epicardial surface, based on a mixture of statistical distributions. Since the formation of the diagnostic value of a medical diagnosis contained in the evaluation of the intensity and nature of the exchange of ionic currents in the myocardium, the work shows the relationship of cumulative density function of the ion currents with the components of the mixture distribution. The model takes into account the characteristic feature of the structure to biological muscle tissue, which is to maintain the size of the individual units of muscle tissue (sarcomere) required for actin-myosin accommodation complex.
