Informative Value of Diagnostic Signs of the Phase Portrait of the Electrical Activity of the Heart in Automated Digital Monitoring

Indicators are recorded and evaluated at a real time with a graphical display in the phase space of coordinates of the relationship between the amplitude and the rate of change of the electrical potential over time, forming a velocity-volume loop when phasography of the electrical heart activity, using digital technologies. As a result, we obtain new features that characterize the speed characteristics of the electrical heart activity, including the inclination angle of the ECG phase portrait. Assessment of the functional reserve level of qualified athletes is informatively carried out on the basis of developed classification algorithms using phasographic indicators of the electrical heart activity. The studied parameters of the cardiac cycle, obtained using innovative digital technologies, can serve as informative signs in the diagnosis of electrical heart activity and personalized indicators of cardiac activity.
