Abstract. In this study we analyze the errors of reconstruction of heart dipole source parameters (position and orientation) from electric potentials measured on
human torso surface. We investigate the effect of selecting human torso model
and number of points in which surface potentials are measured on reconstructed
dipole parameters (dipole trajectories – tracks and dipole moment vector
hodographs). Obtained hodographs are compared with vectorcardiography method,
developed by Ernest Frank. Conclusions about effectiveness of the methods are made on base of calculated reconstruction
