PECULIARITIES OF THE HEART RATE REGULATION AMONG THE POPULATION OF INDUSTRIAL REGION
The impact of environmental factors on the human body is realized in the form of activation of the sympathetic division of the autonomic nervous system. The article included an integrated assessment peculiarities of the heart rate regulation among the population of industrial region.
The investigation objective is а study features of vegetative parameters of people the population of industrial region.
Material and methods. The study involved 129 humans of industrial region of Kazakhstan. The analysis of indicators of heart rate depending population ecologically adverse region.
Results and discussion. Revealed increased tone of sympathetic nervous system. It is indicates the incompleteness and less adaptation of the heart functionality and autonomous control mechanisms of its activities, about the clear mechanisms dominance of extracardiac heart rate regulation.
Conclusion. The results indicate that the population of ecologically adverse region leads to the cumulation of fatigue and overwork in the structure regulation of the heart rate as evidenced the tendency of all indicators change of heart rate towards the sympathetic activation of the vegetative nervous system.
