Abstract

A comparative study of the systemic hemodynamics was carried out in two different age groups of healthy male humans. Cardiac stroke volume was measured on the basis of Teichholz ultrasound echocardiography and computer Fourier analysis of the pulse curve revealed using non-invasive arteriorhythmography method. The aortic blood flow values obtained from ultrasound measurements and reconstructed from volume-clump measurements via transfer functions revealed no significant differences. Age-dependent differences were found out between blood flow curves calculated for the elder and younger groups. The results suggest the possibility of arterioritmographic method for evaluation of hemodynamic parameters of the cardiovascular system in normal state and in pathology, taking into advantage some limitation of this approach.
