HRV may flag acute autonomic shifts from stress in healthy subjects; hypothesis-generating and should not yet change practice.
Does short-term psychological stress produce significant changes in sympathovagal activity measured by heart-rate variability in normal healthy subjects?

Delaney et al. (2000) studied this question.
