Only a single channel is used to record at the same time two curves, i.e., an ECG and a Rheo, from the ascending aorta.
This method makes it possible not only to measure 7 basic volumes of blood in every heart cycle phase, but also evaluate 12 functions of the cardiovascular system performance, so that, based on ANALYTICAL interpretation of the produced data, the relevant cause-effect relations are identified, and decisive pathological factors and their manifestations as a compensation mechanism, maintaining the proper hemodynamics in some phases are discovered, if any. This innovative method allows identifying actual margins in the operation of the cardiovascular system
If exclusively ECG data are used, purely quantified hemodynamic characteristic can be obtained. However, as our investigations show, it is reasonable to support an ECG used for the phase analysis with a rheogram of ascending aorta registered from the same ECG electrodes. This procedure makes it possible to register at one point two signals of different nature at the same time. The first signal is an electric potential characterizing the relevant ECG. The second signal represents mechanical oscillations of blood flow that are indicated in the respective rheogram As our researches show, there are certain regularities between ECG and RHEO interconnections available.
