Does hypnosis improve heart rate variability in patients with major depression?
Hypnosis significantly increases heart rate variability in patients with major depression, suggesting functional improvement in autonomic nervous system regulation.
May support autonomic benefits of hypnosis in depression; leaves open need for RCTs before clinical adoption.
Hypnosis is an adjuvant treatment of major depression (MD). Heart rate variability (HRV) can assess the autonomic nervous system, which is associated with MD, and HRV is decreased in MD patients. There is a lack of research on HRV changes before, during, and after the use of hypnosis in MD patients. A total of 21 MD patients participated in this study, and 5-minute electrocardiograms were recorded before, during, and after hypnosis. Compared with the prehypnotic condition, HRV parameters significantly (p < .01) increased in the hypnotic and posthypnotic conditions. The results suggest that hypnosis treatment should bring some functional improvement to the autonomic nervous system. HRV is potentially a useful tool that quantifies the physiological impact of hypnosis treatment in MD patients.

Chen et al. (2016) conducted an observational in Major depression (n=21). Hypnosis vs. Prehypnotic condition was evaluated on Heart rate variability (HRV) parameters (p=<0.01). Hypnosis significantly increased heart rate variability parameters during and after treatment in patients with major depression compared to prehypnotic baseline (p < 0.01).
