Hardware–Software System for Noninvasive Electrocardiographic Heart Examination Based on Inverse Problem of Electrocardiography

Abstract

Cardiac arrhythmia is an important cause of decrease in life quality and duration. Cardiac arrhythmias are serious medical and social problems. Success in the treatment of cardiac arrhythmia depends on the quality of diagnosis. Electrophysiological mechanism of cardiac arrhythmia and localization of arrhythmogenic substrates are very important for intervention and surgical methods of treatment of cardiac arrhythmia [2]. Invasive electrophysiological examination (EPE) of the heart is the main method of topical and electro� physiological diagnosis of cardiac arrhythmia. EPE is based on direct detection of electrocardiograms at the endocardial or epicardial surface of the heart (endocar� dial or epicardial mapping). Endocardial or epicardial mapping requires detectors to be inserted into the heart chambers or pericardial cavity. Because of invasive char� acter of endocardial or epicardial mapping, this proce� dure should be performed immediately before incision antiarrhythmia treatment of myocardium within the framework of integral surgical or intervention treatment. Development of a noninvasive method for EPE of the heart is an urgent problem. The method should pro� vide electrophysiological information of the same diag� nostic quality as endocardial or epicardial mapping. This method would significantly increase safety and availabili� ty of accurate diagnosis of cardiac arrhythmia. Noninvasive EPE of the heart should be included into the
