NOVEL UNDERSTANDING OF THE PHASIC STRUCTURE OF SYSTEMIC CIRCULATION

Abstract

The article provides novel approach to the phasic structure of systemic circulation for rheovasogramms of upper and lower extremities, based upon neither geometrical description with visual evaluation of rheographic complexes, but upon genesis of their main elements. We reveal systole and diastole of the large circle of circulation analogue to the heart phases. Diastole includes the phases: metabolic (synchronous to the right atrium diastole), pulse wave spread, rapid influx and slow influx. Diastole includes the phases: elastic and muscular outflow, capillary-venous outflow (synchronous to the systolic phase of right atrium). The phasic structure provided can be used for quantitative measurement of biomechanics of the systemic circulation using computed rheovasography, for calculation of the electrical conductivity or resistance parameters and hemodynamics; is able to link biomechanics of the systemic circulation with main arteries kinetics and biomechanics of the heart; to reveal causal interconnections among them, relation of central and peripheral hemodynamics, measure biomechanics of blood circulation in general.
