[Changes in arterial pressure in teenage boys and girls under emotional tension].

In 179 healthy youths and 176 young girls, 4 types of the cardiovascular system responses to the "quanta" of behaviour accompanied by emotional tension, were singled out. Girls less frequently responded with an increase in arterial pressure owing to a peripheral link of the circulation providing a relatively safe adaptation to the stress effects. The greatest changes of the cardiac hemodynamics occurred during "decision making" and "the first success" in girls, and during "socially significant" activity in youths. The used approach permitted to single out subjects predisposed to arterial hypertension.
