[Functional development of the vegetative regulation of the cardiovascular system in human ontogenesis].
Using the functional tests method, it was shown that the ontogenetic course of development of the cardiovascular system vegetative regulation after the age 6 years might be conditionally divided into some periods. About the age of 13-14 years, the spectral structure of heart rate variability reached the level of adult humans but is accompanied with features of functional strengthening in regulative systems. About the age of 15-16 years, maturation of indices received in quiet state (heart rate, stroke volume, spectral and statistical parameters of heart rate variability) is reached. At the same time, the functional maturation of heart rate regulating systems was complete thereby providing adaptive response of the organism during the implementation of functional tests. Functional maturation of peripheral blood pressure and the systems of its regulation completed after 16 years.
