I.info@eco-vector.com15061979603482401202124012021Copyright © 2021, Kirsanov N.I.2021<p>Comparison of the curves of precordial rheograms of velocity and acceleration with ventricular cardiograms revealed their fundamental similarity in shape and time phase intervals. Synchronous registration of rheographic curves of speed and acceleration and differential ventricular cardiograms has an advantage over methods that use only the general rheogram and its first derivative. Obtaining all phases of the cardiac cycle, especially the right ventricle, by a bloodless method makes the technique convenient for use in cardiological studies.</p>показатели фаз сердечного циклареографияЭКГ
