Aims 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. Materials and Several methods were used to influence the metabolism processes in the methods myocardium. The changes in the phase functions of contraction of different cardiac muscles were recorded. In order to have comprehensive influence on the metabolism processes, normalization of the acid-base balance was performed. L-carnitine and octolipen were used to affect the lipid metabolism. Results Phase blood volumes that are characteristic of hemodynamics changed in the course of treatment to reach their nornal values. The ECG shape during the heart cycle phases also changed to reach the norm. The initial ECG shape describing Brugada syndrome almost reached its normal value. Extrasystole disappeared therewith. Conclusion The method of the heart cycle phase analysis enables monitoring any changes in hemodynamics and functions of the cardiovascular system. The method can be used for identifying the original cause of pathologies and efficient monitoring of the treatment progress.

Aims 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. Materials and An original ECG lead of the ascending aorta is proposed. It identifies the methods boundaries of the rapid and slow ejection phases. The concepts and description of the ECG waves are introduced. The amplitudes of the ECG waves are used to characterize the contraction of the muscles of the cardiovascular system segments. Results The general principles of the ECG standardization based on the amplitude analysis of the ECG waves are described. Conclusion Development of the standardization system will contribute to quality improvement of the diagnostics performed by practising physicians.
