RESUMO
The article presents the results of a survey of 62 patients with chronic hepatitis C and 103 patients with liver cirrhosis of viral etiology. Besides clinical parameters studied autonomic features by analysis of heart rate variability at rest and active orthostasis. Indicators of frequency and spectral analysis of heart rate in study patients with chronic hepatitis C and cirrhosis of viral etiology confirmed increase in sympathetic activity and weakening of parasympathetic activity in all respects, with the sympathetic influence of enhanced active orthostasis. Indices of regulatory systems of the autonomic nervous system (stress index and the index of autonomic regulation) also indicated a statistically significant predominance sympathicotonia at rest and active orthostasis, indicating serious violations of adaptation in the examinees.
