Monitoring heart rate variability to assess experimentally induced pain using the analgesia nociception index: A randomised volunteer study

CONCLUSION: ANI did not allow a differentiation of painful, nonpainful or sham stimuli in alert volunteers. Therefore, ANI does not exclusively detect nociception, but may be modified by stress and emotion. Thus, we conclude that ANI is not a specific, robust measure for assessment of pain intensity.
