[Characteristics of circadian variability of heart rate during Holter monitoring].
24-hour Holter monitoring of 60 healthy children aged 3 to 15 years provided criteria for assessing the circadian heart rate (HR) variations as a measure of alterations occurred in autonomic heart rhythm control. Specific HR dynamics during their sleep is described, which involves changes in steady-state rhythm and higher dispersion periods associated with the alternation of slow and fast sleep phases. Sex- and age-related HR features are defined during 24-hour monitoring.
