Abstract

Hemodynamic indices studied in practically healthy people were obtained by catheterization in various vascular areas: the chambers of the heart (ventricles, atria, coronary sinus), pulmonary trunk, aorta, inferior vena cava, superior vena cava, right hepatic vein, and sigmoid sinus. Using the mean values of the hemodynamic parameters, we constructed graphics of the "curves" of the central, arterial, and venous pressure, synchronized with each other and an ECG, and with the radial pulse wave recorded by a non-invasive method. The obtained data, which demonstrate the projection coincidences of the characteristic points of peripheral pulse wave with the key indicators of the phases of cardiac cycle (CC), made it possible to transform the results obtained during the invasive examination into indicators of the non-invasive technique. This transformation became possible not only at the characteristic points of the deployed peripheral pulse wave, but in each anacrotic and dicrotic segment, which are understood as the projection areas of the synchronized hemodynamic and wave processes of the vascular bed. We believe it possible to catalog the forms of pulse waves, as well as their projection segments, to obtain accurate diagnostic information about the phases of CC and organ hemodynamics in humans in norm and with pathological conditions, using a non-invasive methood based on basic information obtained by invasive methods.
