Peculiarities of spectral parameters of EEG, HRV and routine parameters of immunity in patients with various levels of the entropy of EEG, HRV, immunocytogram and leukocytogram

Journal of Education, Health and Sport, 2019
Background. We have previously shown that the entropy levels of spectral parameters of EEG and HRV as well as of Immunocytogram and Leukocytogram are well dispersed. The method of cluster analysis was the distribution of the observed contingent into four

Features of the HRV, endocrine and metabolic parameters in persons whose immune status is susceptible or resistant to chronic stress

Journal of Education, Health and Sport, 2020
Background. In the previous studies, we compared the individuals who were almost identical to the average value of LF/HF ratio and its dispersion, but with opposite deviations from the norm of immunity.
