Аннотация
Исследуется степень зависимости вариабельности ритма сердца здоровых юношей и девушек от величины средней частоты ритма. В изученной группе молодых людей вариабельность сердечного ритма снижалась с увеличением частоты сердечных сокращений. При одинаковом увеличении частоты сердечных сокращений у девушек вариабельность сердечного ритма снижалась меньше, чем у юношей. Увеличение средней частоты сердечного ритма на 10 кардиоциклов в минуту уменьшало вариабельность сердечного ритма у юношей на 25,6 мс, а у девушек — только на 14,9 мс. Сделано предположение, что причина этих различий — разный гормональный фон в исследуемых группах.
Abstract
In this article, we study the degree of dependence of heart rate variability in healthy adolescents and young adults on the average rhythm frequency. In the study group, heart rate variability decreased as heart rate grew. Although there was no difference in the increase in the heart rate, the variability of the heart rate decreased less significantly in young women than in young men. An increase in the average heart rate by 10 cardiac cycles per minute reduced the heart rate variability by 25.6 ms in young men and by 14.9 ms in young women. We believe this to be a result of differences in the hormonal backgrounds within the study groups.
