The balance of the autonomic nervous system in post-MI diabetic patients on indicators of heart rate variability

Abstract

The article presents the results of the study of heart rate variability (HRV) in postinfarction patients with type 2 diabetes mellitus according to a 24-hour ECG monitoring.  It was found a significant reduction in the absolute majority of statistical and spectral parameters of HRV, indicating a decrease in total activity neurohumoral effects on  heart rate with the weakening of sympathetic and parasympathetic regulation. Thus, the ratio of regulatory systems in postinfarction diabetic patients was marked  imbalance of the autonomic nervous system with the relative predominance of sympathetic influences over the parasympathetic, which was especially important at  night.
