The peculiarities of the heart rhythm regulation were investigated in humans during the processing of acoustic information. Statistically significant differences were found in individuals with different levels of auditory-motor reactions according to the heart rhythm characteristics. Individuals with the high level of reactions were characterized by significantly lower total power spectrum (TP=1276.2 ms2), by the power spectrum of high (HL=280.1 ms12) and very low frequencies (VLF-469.8 ms2), as well as by low indexes of standard deviation of R-R intervals (SDNN=37.4 ms), when compared with the persons with the low level of reactions (5248.8; 866.7; 1937.0; 69.8 ms2). The correlation analysis confirmed the dif- ferences between the groups ol persons with adtierent number of processed information and variable (r=0.41, P0.05) and spectral characteristics of heart rate (r=-0.49--0.56, P0.05). Different strategies of activation of non-specific brain systems in formation of psycho-physiological reactions and participation of heart rhythm regulatory mechanisms in vegetative support of auditory information processing are discussed. |
