Abstract

Differences in cardiointervalogram parameters have been revealed in young people with the morning and evening chronotypes. Individuals with the morning chronotype are characterized by a tendency to sympathicotonia in the morning, which decreases towards the end of the day. For individuals with the evening chronotype, a reverse tendency is typical, which is manifested as the appearance of signs of cardiointervalogram sympathization in the evening.
