Features of carrdiac rhythm variability in teenagers 10-14 years whom have suffered hypoxic-ischaemic encephalopathy

The features of cardiac rhythm variability in teenagers 10-14 years whom have suffered hypoxic-ischaemic encephalopathy moderate severity are investigated. The changes in spectral and temporary parameters of cardiac rhythm variability in these children indicate they have increased the initial activity of the sympathetic division of the autonomic nervous system (ANS); reducing the integral influence of autonomic regulation mechanisms, tone and reactivity of the parasympathetic branch ANS, increasing intensity of activation of sympathoadrenal system in transition from horizontal to vertical position.
