Heart rate fluctuations in schoolchildren with various types of autonomic activity

In schoolchildren with normo- and hypersympathicotonic types, autonomic reactivity is increased, and in individuals with an asympatheticotonic type of reaction, it decreases. The process of restoration of cardiac activity is accompanied by the activation of an autonomous regulation loop with a predominance of sympathetic modulations, and in schoolchildren with a hypersympathicotonic type of autonomic reactivity, the activity of the central regulation loop and humoral factors also increase.
