Scientific approach to physiological interpretation of heart rate variability spectral analysis
The heart rate variability analysis method is efficiently operated in different spheres of medicine for the matters of risk stratification and pathologic conditions’ diagnostics for the patients with cardio-vascular diseases. The method is also exerted for the control of sportsmen’s functional condition. According to the specialists’ opinion, at the current instant there is existence of the problems in heart rate variability evaluation. One of them - methodology standardization, which requires a distinction of electrocardiography registration conditions, deciding on which indexes and methods of heart rate variability analysis are the most informative and what are the normal values for groups of different age and sex. Another problem is connected with the physiological interpretation of the heart variability method, its specifics and predictable ability for both sick and healthy people. In the article there are reviewed theoretical and experimental bases of the new approach to the physiological interpretation of the heart rate variability spectral analysis, which gives a reason for a reexamination of some of the current versions. In experiment, the dynamics of indicators of short records after influence of the following means was traced: cross-country skiing, run, the bicycle, swimming, week-long training occupations pupils of 13-17 years on track and field athletics and volleyball.
