Development of noninvasive topical diagnostics of cardiac arrhythmias

Heart arrhythmias may accompany virtually any cardiac disease. The problem of the preprocedure topical diagnostics of various arrhythmias remains fundamentally important and relevant, which is confirmed by numerous algorithms aimed at non-invasive detection of the arrhythmogenic focus location. Today, many different methods are available for non-invasive topical diagnostics of the arrhythmogenic foci in both ventricular and atrial arrhythmias. A non-invasive imaging of cardiac electrophysiology (NICE), based on the solution of the inverse problem of the electrocardiography, is the most advanced new technology. The accuracy of NICE reaches 90%, however, it is still inferior in its capabilities to the “reference” method of the invasive intracardiac electrophysiological examination. Currently, the market presents devices for both invasive mapping and NICE. However, in the context of surgery, an integrated system of non-invasive electrophysiological mapping with invasive three-dimensional electroanatomic mapping is of high demand. The creation of hybrid systems will allow to visualize electrophysiological processes in the epi- and endocardial surface in the real time with very high accuracy and to carry out the radiofrequency catheter ablation of arrhythmias with the simultaneous reduction of the radiation load on the patient and medical personnel.
