HEALTHY CHILDREN FROM 6 TO 16 YEARS' HEART RATE VARIABILITY
Abstract
The cardiorategrams of 5400 children from6to 16 years was analyzed for studying of age features of heart rate variability. It was revealed, that those children's values of parameters of heart rate (M, SDNN, RMSSD, TP, VLF, HF) was increased with age. It was accompanied by sinuosity fluctuations of parameters from year to year. Gender differences were observed on parameter of M since 9th years old, on parameters TP, VLF, LF since 11th years old, on parameters SDNN, RMSSD, HF since 12th years old. It was not revealed gender differences at the age of 16 years on all parameters of heart rate variability. It was shown, that parameter VLF received on the record of the electrocardiogram with duration less than five minutes was suitable for a physiological and clinical evaluate. The received values of parameters can be used in practice as normative.
