The Development of LF/HF Ratio and its Dependence on the Mean Heart Rate in Children and Adolescents

Popis výsledku v původním jazyce

We have shown previously how the dependency of the baroreflex sensitivity on the inter-beat intervals (IBI) can cover up the developmental changes. Therefore we decided to analyse LF/HF ratio. We have calculated mean IBI and heart rate (HR) and their power spectra in 424 subjects (11 - 20 years) from the 5-min continuous blood pressure monitoring at rest. LF/HF ratios of IBI and HR spectra were determined. The statistic was done for a whole group (WG), and for subgroups of older children (C:11-15 years), adolescents (A:16-20 years), and for 10 particular age-subgroups. In the WG and the A, we shown significant relationship between age and mean IBI or HR, but LF/HF IBI or LF/HF HR were age-independent. LF/HF IBI or LF/HF HR was also significantly age-dependent. Negative correlation of IBI vs. LF/HF IBI and a positive correlation of HR vs. LF/HF HR in the WG and in C or A was found. Relationship IBI vs. LF/HF IBI and HR vs. LF/HF HR were in particular age-subgroups from 11 to 14 years, b
