[The relationship of preoperative emotional stress in children to the type of autonomic regulation of the heart rhythm].

Psychophysiological characteristics of the emotional stress reaction have been studied preoperatively in 31 patients aged 3 to 14 years. The dependence of the nature and depth of peroperative stress on the type of autonomous cardiac rhythm regulation has been established. Psychophysiological differences in the reaction of children with distinct types of autonomous regulation to standard premedication (promedol and atropine) have been observed.
