Background. We consider a method for increasing the effectiveness of noninvasive cardiodiagnostics, based on the transition from multichannel electrocardiosignals and related electrical potential distribution maps on the torso surface to the spatial-temporal characteristics of the equivalent electric heart generator (EEHG).
Materials and methods. We carry out reconstruction of the distribution of the equivalent electrical heart sources of the cardiac cycle. When processing we use both recorded electrocardiosignals and the coordinates of the electrodes, placed on the human torso surface.
Results. We obtain maps of electric potential distributions on the heart surface at various time points for surface type EEHG and spatial tracks of the temporal dynamics of the heart electrical activity in the volume of the heart for dipole type EEHG.
Conclusions. The results of the EEHG reconstruction show the possibility of observing the spatio-temporal dynamics maps of the electrical heart activity and are intended to increase the informativeness of electrocardiographic examinations.
