FEATURES OF HEART RATE VARIABILITY IN CHILDREN WITH NEUROCULATORY CARDIAC DYSTONIA
Keywords:
schoolchildren, neurocirculatory dystonia, cardiac rhythm and conduction disorders.Abstract
The article evaluates circadian rhythms and heart rate variability in urban and suburban adolescents with similar neurocirculatory dystonia. In children with neurocirculatory dystonia (NCD), a decrease in parasympathetic effects was found using the heart rate variability method. In children with NCD, the overall influence of regulatory factors on heart rate and overall variability of cardiac intervals during orthostatic examination, activity and reactivity of the parasympathetic division of the autonomic nervous system were lower than control values with increasing stress. index. The observed changes in circadian rhythm and rhythm variability in urban adolescents compared to rural adolescents are associated with living in an industrial area, environmental criteria, diet and additional information load, which is essential for further research.
