title: [Parameters of circadian heart rate variations, night sleep profile and structure during the Holter monitoring procedure in the groups of students with different adaptation potential].
abstract: Circadian heart rate variations, night sleep profile and structure during ECG Holter monitoring process have been studied in practically healthy students with various adaptation potential to estimate the role of the dynamics of these parameters for evaluation of functional condition of cardiovascular system and whole organism. Statistically significant differences have been revealed for the functionally distinguished groups for the following parameters: P average/day, Circadian Index, sleep profile and sleep duration. When the mechanisms of adaptation are very strained, P average/day is high and circadian profile is strengthened, which indicates to the increase of sympathetic influence on the heart rhythm in persons who have primary high level vagotonia. With increasing of the strength of the adaptation mechanisms the sleep duration (sleep profile as well) is reducing, which may be one of the causes of asthenization.
