Abstract
The aim of the study was to reveal the patterns of the age-related dynamics of the frequency-dependent regulation of heart rate variability (HRV) based on the analysis of Holter ECG recordings from healthy subjects of four age groups: neonates, one-year-old infants, adolescents, and adults. A wide spectral composition of HRV is shown, consisting of nine Hilbert-Huang modes in the frequency range from 0.0001 to 2 Hz. A decrease in the central frequencies of all modes is shown in the postnatal period with a plateau in adolescence. A rapid progression of systemic humoral regulation of HRV, characterized by a consolidated increase in the amplitudes of the corresponding modes with a plateau in adolescence, is demonstrated. The dome-shaped character of age-related changes in amplitude of modes associated with autonomic control with a maximum in adolescence is shown. The results obtained quantitatively demonstrate age-related consolidated changes in HRV parameters from neonates to adulthood.
期刊介绍：
Doklady Biochemistry and Biophysics is a journal consisting of English translations of articles published in Russian in biochemistry and biophysics sections of the Russian-language journal Doklady Akademii Nauk. The journal''s goal is to publish the most significant new research in biochemistry and biophysics carried out in Russia today or in collaboration with Russian authors. The journal accepts only articles in the Russian language that are submitted or recommended by acting Russian or foreign members of the Russian Academy of Sciences. The journal does not accept direct submissions in English.
