[Cardiac contraction frequency in Macaca rhesus monkeys occupying different position in a group hierarchy].

Four variants of heart rate ratio were revealed in 8 groups of the monkeys of different hierarchic positions. Dependence of the heart rate in low-ranking monkeys on the character of their interrelationships with the dominant individual, was shown. The lowest heart rate was revealed in the monkeys protected by the drominand individual. The heart rate at rest and its shifts during feeding reflect the degree of emotional tension in monkeys of different ranks.
