Cardiocode diagnostic

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.

Basic relationships of ECG & Rheo phases

The essence of these relationships is that a certain regular succession in mutual re-distributing of determining factors between the ECG & Rheo phases occurs. So, the PQRSL complex shall be treated to be the determining factor responsible for generation of a difference in aortic pressure between the aorta and the peripheral portion of the blood vessels. The LjTi complex determines the period of formation of blood flow structure.
Therefore, knowing the above relationships of the phase transitions of ECG and Rheo, the appropriate data can be obtained such as what is the price paid for maintenance of normal quantified parameters in hemodynamics generally, or what is the cause of a pathology expressed in certain symptomatology.
