[Cardiac rhythm in children with emotional stress].
The cardiointervalogram was recorded in 97 children during their stay at the surgical hospital for inguinal or umbilical hernia. The investigation was carried out on day 1 of the child's hospitalization, on the day of operation (30 minutes before premedication) and on the eve of the discharge from the hospital. It has been shown that the negative emotions occurring in the child during stay at the hospital produce considerable changes in the mechanism by which the cardiac rhythm is regulated, interfering with vegetative balance and thus prompting the sympathetic part of the vegetative nervous system to exert a greater influence on the child's body. The tension of the regulatory mechanisms in emotional and stressogenic situations rises with the child's age. The age-associated differences have been revealed in the children's sensitivity to emotiogenic stressful factors of varying nature.
