[Autonomic innervation in newborn infants according to interval cardiography]

Altogether 48 full-term neonates were examined for vegetative supply with the aid of cardiointervalography performed at different stages of the consciousness-sleep cycle. It was established that the process of early adaptation was accompanied by the potentiation of the influence of the central contour of heart rhythm regulation. During feeding, a certain weakening of the adrenergic mechanisms was recorded. The cry was characterized by heart rhythm stabilization with an excess activation of the sympathetic part of the vegetative nervous system. Some characteristics of vegetative supply were defined on transition from sleep to being awake and during feeding in healthy children on days 1, 3 and 5 of life. The data obtained can be used for characterization of the vegetative homeostasis in full-term neonates.
