Abstract

Previous research has suggested that heart rate variability (HRV; the variability in the interval between successive heartbeats) can predict the perception of experimentally-induced pain (i.e., pain sensitivity). However, little research has sought to investigate sex-specific associations between HRV and pain sensitivity. This is an important consideration, given that sex differences in resting HRV have been observed, and there has been extensive debate about sex differences in sensitivity to experimentally-induced pain. We examined whether the association between resting HRV and sensitivity to experimentally-induced pain differed in men and women. Fifty-one pain free individuals (26 women, ..
