The method allows to diagnoze the following hemodynamics volumetric characteristics applying ECG single-channel lead: SV - stroke volume of blood, ml; MV - minute stroke volume, l; PV1 - blood volume flowing to heart ventricle during diastole phase, ml; PV2 - blood volume flowing to heart ventricle during atrial systole phase, ml; PV3 - blood volume ejected by heart ventricle during rapid ejection phase, ml; PV4 - blood volume ejected by heart ventricle during slow ejection phase, ml; PV5 - blood volume (SV portion) transfered by ascending aorta acting like a peristaltic pump, ml.
