The studies were conducted on the first day of hospitalization in both groups of patients in the clinic. These data were compared with the norms of the corresponding options of heart rate variability and among themselves. The results indicate a significant autonomic dysfunction in patients with chronic alcohol dependence. The study determined the correlation between heart rate variability and hemodynamics in both groups.
