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.

Capabilities of the cardiometric diagnostics based on the heart cycle phase analysis for identifying the primary cause of a disease are considered in this paper.

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.

Up to the present, ECGs have been classified on the basis of the analysis of the ECG curve shape. But this made impossible to classify many ECG shapes. The most promising methods for the classification must evaluate each of the 10 cardiac cycle phases both by their functions and hemodynamic parameters. The aim hereof is to develop the new classification principles for all possible ECG shape variations.

A cardiac muscle performance assessment in terms of acid-alkaline balance has never been carried out before. The studies show it is possible to evaluate indirectly aerobic, anaerobic and phosphocreatine processes in the cardiac muscle using ECG only. The aim is to study the capabilities of acid-alkaline balance measurement in the cardiac muscle using ECG only, in combination with the heart cycle phase analysis.

Attempts to create an artificial heart were highlighted by our journal one year ago. Now we can say that there is no break-through news in this field: no technological progress, no pioneering research and no spectacular advancements are reported.

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.

The paper is devoted to research and development of a new, based on Multiscale Correlation Analysis method of PVC (premature ventricular complexes) extra beats and SPB (supraventricular premature beats) online detection.
