title: [Cardiac rhythm in pupils during tests].
abstract: Variation pulsometry was used to study changes in the activity of cardiac rhythm regulating mechanisms in third-form pupils from a comprehensive school (a control group) and a gymnasium (a study group) under mental stress caused by the performance of mathematical tests. Two types of responses of the studied parameters: sympathetic (in the study group) and parasympathetic (in the control group), which were determined by the richness and intensity of an academic load and by the readiness of both categories of school-children, were identified.
