CARDIOVASCULAR SYSTEM ABORIGINAL AND SEND THE FEMALE CARDIOVASCULAR SYSTEM ABORIGINAL AND MIGRANT FEMALE POPULATION OF THE NORTH OF RUSSIA: MODELS AND AGE DYNAMICS
Pathology of the cardiovascular system significantly affects the operational period, and improvement in cardiovascular system always and definitely can provide the prolongation of life. So the study of differences in life expectancy between aboriginal and migrant female population living in the North of the Russian Federation is based on the state of the cardiovascular system. To study the dynamics of the parameters of the autonomic nervous system in female population of Ugra - Ob of the North of Russia, the authors used the method of cardiorythm registration. It is defined that parasympathetic division (parameter SIM) dominates over the sympathetic division (parameter PAR) of the autonomic nervous system in the youngest age group of women. The authors found diametrically opposite dynamics of PAR in two age groups: migrant population has a high initial value at a young age (12.5.a.u.) in comparison with the natives (10,6 a.u. source). However, in older age, these differences remain (7,84 a.u. and 6,87 a.u. respectively). Description of the dynamics of increase of the sympathetic and downs parasympathetic effect was produced in the framework of the model of Verhulst-Pearl, i.e., systems with saturation. However, the parameters of RR-intervals in the migrant population have a parabolic dependence.
