Evaluation of Three Dimensional Motion of Mass Center of the Heart by Electrical Impedance Mapping

The development of non-invasive methods and means of monitoring the hemodynamic characteristics of the activity of the heart are relevant today. This paper evaluates the possibilities of precardial electrical impedance mapping of the heart. The possibility of registering the trajectory of the mass center of the heart during the cardiac cycle is considered. An algorithm for processing electrical impedance signals is proposed, which makes it possible to calculate the trajectory of blood volume in the heart from electrical impedance signals of radial electrical impedance mapping of the heart. The trajectories of the center of mass of the heart (blood in the heart) for three healthy volunteers of asthenic, normostenic and hypersthenic physique were obtained.
