Variability of heart rhythm in young men in Yakutia depending on seasonal changes of atmospheric parameters

摘要

A comparative analysis of the heart rate variability (HRV) parameters in healthy Yakut youths in different seasons of theyear revealed high-sensitivity heart rate parameters: RMSSD is the root of the square sum of the differences inconsecutive RR intervals, the power of the high frequency (HF) and low frequency (LF) components. These indicatorscharacterize the features of vegetative regulation of the heart during seasonal fluctuations of meteorological factors in theconditions of the extreme climate of Yakutia. The study of the individual seasonal dynamics of HRV characteristicsshowed that youngest men show the dependence of the parameters on the time of the year. However, these dependenciesare individual.
