SPECTRAL INDICATORS HEART RATE VARIABILITY IN CHILDREN WITH ASTHMA DURING EXACERBATION AND REMISSION
The results of the comparative analysis of autonomic nervous system condition in patients asthma during the period of both aggravation and remission of the disease are presented. The 121 patients are examined in the study (81 during the period of an exacerbation of a disease and 40 during the remission). According to the spectral analysis of heart rate variability in children of both groups the predominance of slow waves II order were noted in spectrogram, it testifying to increase of humoral-metabolic effects. The VLF waves made 2700,275 ± 248,35 мс2 values spectral power averaged in children during the period of remission of the disease. The vagosympathetic balance factor (LF/HF) in 33,3 % of patients experiencing an attack of asthma and in 42,5 % of patients during the remission of the disease is greated than 2,0, it indicating activation of sympathetic nervous system. Analyzing the data one can say that the findings of the spectral analysis of heart rate variability in children with asthma are early markers of abnormal autonomic regulation.
