The establishment of the features of the change in the indices of the functional state of the organism under the influence of the multifactorial environment of children is a complex process since the level of any system is supported by a number of compensatory mechanisms, based on the multiparametric interaction of organs and body systems. In this regard, the search for a “weak link”, which, first of all, undergoes changes in the system of regulatory processes for maintaining homeostasis, is topical. The analysis of data on the variability of cardiac rhythm in children aged 7-10 years exposed to complex effects of intraschool environment factors in accordance with a comprehensive assessment of the learning and upbringing conditions within 670-679.5 points and environmental factors, the total anthropogenic load factor of which was within 10.5 -25.8 units revealed no specific changes in statistical indices of the cardiac rhythm variability due to the inclusion of a complex of compensatory mechanisms, which are the basis for multiparametric interaction of the body’s functional systems aimed at maintaining a certain level of functioning of the cardiovascular system, sufficient to adapt to changing environmental conditions a habitat. The established signs of the autonomic dysfunction in children aged 7-10 years in conditions of the comprehensive influence of the factors of the educational process, learning conditions and the environment can testify to the development of disadaptive reactions in the organism of the schoolchildren under study
