Aims

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.

Materials and methods

Cardiometry is based on the mathematical model of hemodynamic processes. The model is described by G. Poyedintsev and O. Voronova equations. The variable values in these equations are the cardiac cycle phase durations recorded on the ECG. An original ECG lead of the ascending aorta reflects all the processes of the heart performance. Thus, it is possible to calculate the phase blood volumes. This method is an accurate indirect measurement method. The synchronous recording of the ascending aorta ECG and Rheogram enables monitoring of the compensation mechanism responsible for the normal hemodynamic performance.

Results

An innovative mathematical model of hemodynamics providing the creation of an innovative indirect method for measurement of the cardiovascular system parameters was developed.

Conclusion

The innovative method of cardiovascular system diagnostics enables to measure 7 main hemodynamic parameters using noninvasive technology for qualitative evaluation of 12 functions of cardiovascular system performance and general assessment of coronary flow status.
