Abstract:
The article evaluates the results of autonomic nervous regulation in preschool children with different
psychological status through the analysis of heart rate variability. We examined 127 children aged 3,8–5,5
years. The average statistical indices describing the regulation of the heart rhythm in preschool children with
neuroses, predoneuroses, anxiety and normally developing have been determined. Preschoolers with neurosis
were characterized by significantly higher temporal HRV values: heart rate, heart rate, activity index of
regulatory systems, SI. The changes in the regulation of the heart rhythm have been established, which testify
to the strengthening of the sympathetic contour of regulation in children with neurosis, the immaturity of the
parasympathetic department of the central nervous system, reflect the stress of the regulatory systems, and
also indicate a decrease in the reserve capacities of the organism.
