RECONSTRUCTION AND VISUALIZATION OF THE HEART ELECTRICAL ACTIVITY USING A MULTIELECTRODE SYSTEM FOR ELECTROCARDIAGNOSTICS

Abstract

Background. We consider the medical information system for non-invasive electrocardiodiagnostics, based on the registration and processing of electrocardiosignals from multielectrode leads. To improve the reliability of heart diseases diagnosing in electrocardiological screening, it is proposed to dynamically visualize maps of the heart electrical activity on the surface of the epicardium. Materials and methods. We propose the functional diagram of an information multielectrode screening system for electrocardiodiagnostics. The distribution of electrical potential on the heart surface during the cardiocycle is reconstructed. Within processing, both the recorded electrocardiosignals and the coordinates of the electrodes, placed on the human torso surface, are used. Results. We evaluated the number and location of electrodes on the torso surface. The data transfer rate was determined during the registration of multichannel electrocardiosignals. The features of 2D visualization for maps of the heart electrical activity are considered. Conclusions. The medical information system for non-invasive electrocardiodiagnostics provides an opportunity to observe maps of electrical activity on the heart surface, changing synchronously with changes in the electrocardiogram. The usage of several sizes vests with pre-installed electrodes allows us to reduce the time of installation of electrodes for using the system in screening surveys.
