[Course of heart beat variability following acute alcohol intake]

Blood pressure, heart rate and mean momentary arrhythmia were measured in 16 healthy test persons before and after acute alcohol ingestion. While the blood pressure remained unchanged, heart rate and mean momentary arrhythmia showed significant differences in comparison to the initial value, in which case the clearer change of the mean momentary arrhythmia in relation to the heart rate emphasizes the sensitivity of the parameter. The results are discussed as a sequel of the increase of sympathetic activity of alcohol/acetaldehyde.
