An algorithm for electrocardiosignals processing in a multielectrode electrocardiological screening system for visualization of the electrical potential of the epicardium

An algorithm for processing electrocardiosignals in a multielectrode screening system for electrocardiodiagnostics, focused on visualization of the epicardial potential, is proposed. The stages involved in the processing of electrocardiosignals in the multielectrode electrocardiological screening system using a multichannel electrocardiosignal recording unit based on a vest with preinstalled electrodes are presented. An approach is proposed for defining the center and orientation of the coordinate system used for describing the surface of the epicardium by processing the electrical potential map on the surface of the torso. Results obtained by applying this approach are presented. Features and examples of the visualization of 2D electric potential maps on a spherical quasi-epicardium are considered.
