Does electro-acupuncture at PC5 and PC6 alter heart rate variability in healthy volunteers exposed to fear-invoking auditory stimulation?
Answers are grounded in this paper and cite their sources.
Electro-acupuncture at PC5 and PC6 increases parasympathetic activity markers of heart rate variability in healthy subjects exposed to fear-invoking stimuli.
Background: Fear is one of the most widely studied emotions and is closely associated with the autonomic nervous system (ANS). Previous studies have proven that acupuncture directly impacts the ANS, influences the heart rate (HR) and the heart rate variability (HRV) and exerts other effects. The aim of this study was to explore the effect of Jianshi (PC5) and Neiguan (PC6) electro-acupuncture on HRV during fear-invoking auditory stimulation using an Actiheart ECG recorder.

Huang et al. (2017) conducted an RCT in Healthy volunteers exposed to fear-invoking auditory stimulation (n=105). Electro-acupuncture at Jianshi (PC5) and Neiguan (PC6) vs. No intervention was evaluated on Root mean square successive difference of N-to-N intervals (RMSSD) during electro-acupuncture (p=0.011). Electro-acupuncture at PC5 and PC6 significantly increased the RMSSD (63.90 vs 46.35, p=0.011) and high-frequency components of heart rate variability in subjects exposed to fear-invoking auditory stimulation.
