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.

Basic criteria of finding the markers of the hemodynamic self-regulation mechanism on an ECG and a Rheogram are described herein. The basics of an analysis of the compensation mechanism responsib le for the maintenance of the hemodynamic parameters within the norms are presented in this paper.

This paper deals with a study of central hemodynamics in 363 pediatric patients with burn shock as compared with a reference healthy children group in order to establish clinical value of the hemodynamic parameters for burn shock diagnostics and therapy.

The interrelation between hemodynamic changes, functions of the cardiovascular system and biochemical reactions in the cells of the heart muscle is investigated in the present paper.

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.

The article considers the development of the periodic table of ECG phase changes which should reflect the variety of the ECG curves and can be used as reference system for diagnostics purposes.

Conventional methods for arterial pressure (AP) measurement are not capable of identifying it in each cardiac cycle. Besides, they ignore many significant factors. The paper reports on an innovative method based on cardiac cycle phase analysis for detecting systolic and diastolic AP changes in each cardiac cycle using synchronous digitally processed ECG and Rheo recordings. Considered is the phase mechanism of the natural diastolic pressure regulation. The diastolic AP changes referred to the physiological norm and aortic dilatation status are also assessed.

Diagnostic parameter “arterial pressure” known in medical practice from the earliest times is now widely used for assessment of body state. Indirect occlusive methods are the most popular measurement techniques. Although the indirect method of measurement is more than one hundred years old there is no precise understanding of biophysical processes taking place in compressed blood flow.

The paper reviews the existing methods for hemodynamic parameters measurement, namely the Fick method, the thermodilution technique and the Cardiocode technology. Comparative analysis of the above methods is presented. Strong and weak points in each method and their informative values are identified. Distinctive features of the Cardiocode method, as the only noninvasive one, are described.
