The article aims at describing the theoretical principles of cardiometry as a fundamentally new scientific field which enables the accurate measurement of the cardiovascular system parameters.
The article aims at describing the basic system criteria of the ECG interpretation on the basis of the cardiac cycle phase processes as well as systematizing these criteria for developing new standards for the ECG classification.
Criteria of identification of individual heart cycle phases according to an ECG curve are described in this paper.
The results of study of an artificial aortic valve by the heart cycle phase analysis are given in the paper. The main aim of the study is identifying the artificial aortic valve influence on cardiovascular system functions, the way and ranges of these functions change. The results of phase blood volume measurement and the numerical values that characterize the metabolic processes in heart muscles are given herein.
