Arrhythmias' prognosis with temporal and spectral heart rate variability analysis in patients with severe alcohol intoxication

Abstract

Spectral and temporal parameters of heart rate variability in patients with severe alcohol intoxication were analyzed in short-time ECG recording, as well as during 24-hour ECG monitoring. Individuals with acute alcohol heart injury and ventricular arrhythmias had reduced heart rate variability, comparing with patients not demonstrating life-threatening ventricular arrhythmias. The most powerful predictors of heart rate variability disturbances were spectral parameters in brief ECG fragments, and temporal characteristics - in 24-hour ECG monitoring.
