Combination of substantial high-quality morfofunkcional'nykh transformations of myocardium and influence of external factors can unfavorably affect the state of health of man.
For 7-10-years-old schoolboys 0,67-0,72 made duration of one cardiac cycle with and for certain increased to 11-14: for girls - on 0,09 with (r<0,001), for boys – on 0,12 with (r<0,001). At the exposure of reliable distinctions between boys and girls were found out more high indexes for boys in 7-10 years (r<0,05) and 11-14 years (r<0,01). It was set that parameters of attractors of vector of the state of organism of schoolboys khanty had gendernye features and raznonapravlennuyu age-dependent tendency.
So in 7-10 years for girls a general volume of multidimensional parallelepiped was 4,69e+045, and index of asymmetry of rx=20,52, while in the group of boys volume of multidimensional parallelepiped on ten orders less than and 1,60e+035 made.
In the groups of schoolboys 11-14 years of distinctions in the studied parameters are not exposed, while in 15-17 years for boys khanty of General V value: 2,67e+034, rx=22,37, that on thirty orders more than for girls khanty of this age.
Thus, the different age-dependent dynamics of excitability of myocardium of auricles and ventricles is set for schoolboys khanty 7-17 years. For girls in a midchildhood indexes demonstrated khanty more high, than for boys excitability of myocardium of auricles and its progressive decline to 15-17. For boys khanty a reverse tendency is marked. The function of excitability of myocardium of ventricles prevailed for boys both in 11-14 and 15-17 years (r<0,05). Duration of atrioventrikulyarnoy conductivity actively went down to 15-17 in both sexual groups, but for girls khanty speed of leadthrough of excitation on AV was a knot a few slower.
