[Functional tests for the assessment of the healthy people state using heart rate variabilIty]

An overview of current approaches to interpreting the results of spectral analysis of heart rate variability and blood pressure is demonstrated. The analysis of own obtained results were done using the method of assessment of heart rate variability and blood pressure in a variety of functional tests (mental load, moderate exercise, cold test, the restriction of pulmonary ventilation, controlled breathing at a frequency of 6 cycles per minute) in healthy adults. It was shown that all tests induced pronounced changes in the spectral indices of heart rate variability as well as the blood pressure, which were interpreted as changes in the state of autonomous regulation of subject's cardiovascular system. The direction and the degree of changes depend on the form of action.
