Analysis of heart rate variability started to develop in the USSR in the early 60-ies. An important incentive for its development was the success of space medicine (Parin V. V., Baevsky R. M., Gazenko O. G., 1965). Currently, however, most Russian researchers uses proposed in 1996 by the European Society of Cardiology and North American Electrophysiological Society standards of measurements, physiological interpretation of HRV and recommendations for the clinical use of this method (Heart rate variability, 1996), which do not take into account the vast experience of domestic science.
One way or another, but in most cases the analysis of heart rate variability used for diagnosis, although the nature of this phe-nomenon can be considered from the point of view of optimum movement of blood in the appearance of a specific local consumers. Accordingly, the heart rate variability can be interpreted as one of natural phenomena, imparts unique properties to the car-diovascular system. This allows, for example, to consider the processes associated with heart rate variability, as a way to increase local blood flow in areas that have the ability to modulate heart rate at frequencies below the heart rate. The most striking example of this effect is respiratory arrhythmia, which is expressed in changes (modulation) in heart rate breath rate – 5-6 heart beats in one breathing cycle. The mechanism of this phenomenon is that when the work of the respiratory muscles affected through the nervous system, forcing the heart to change its rhythm and produced modulation of heart rate.
The meaning of this modulation can be explained assuming that at the top of the breath ends with the opportunity to lead an active oxygen exchange in the lungs and the pulmonary circulation begins to exhale, which is \"idle\". The heart slows down the beats, because the activity of metabolic process falls and abundant blood flow is not required. Thus, the cardiovascular and respiratory systems provide maximum efficiency of the exchange process, while maintaining low energy consumption for pumping blood through the pulmonary circulation.
In this article, the authors attempt to improve the model of the effect of increasing local blood delivery to take into account low-frequency modulation of heart rate, the most typical of which is the modulation of the respiratory process. Then there is the possibility to combine the mechanism of action pulse of the consumer (e.g. leg muscles when you walk) and respiratory system and increase the effectiveness of the massagers of different systems, using modern Metrology tools (e.g., sensors of the pulse wave) and closing them on the outside of the pacemaker of respiration.
