Key result
Two standard drinks of either red wine or ethanol increased heart rate (P<0.001) and decreased total heart rate variability by 28-33% (P<0.05), reflecting augmented sympathetic modulation.
Why the study?
Does red wine or ethanol alter heart rate variability in healthy subjects?

Acute moderate alcohol may augment sympathetic tone in healthy adults; leaves open arrhythmia risk implications.
Spaak et al. (2010) conducted an RCT in healthy subjects (n=12). Red wine and ethanol vs. Water was evaluated on Heart rate and heart rate variability (p=<0.001). Two standard drinks of either red wine or ethanol increased heart rate (P<0.001) and decreased total heart rate variability by 28-33% (P<0.05), reflecting augmented sympathetic modulation.
