Key result
Auricular acupuncture significantly changed total heart rate variability (P=0.025) and ST36 stimulation decreased the low-frequency/high-frequency ratio (P=0.03) in anesthetized rats.

Does acupuncture of the ear and body alter heart rate and heart rate variability in anesthetized rats?
p-value: p=0.025
Auricular acupuncture significantly increases total heart rate variability in anesthetized rats, suggesting a modulatory effect on autonomic function.
Gao et al. (2012) studied Anesthetized rats (n=10). Acupuncture of the ear and body was evaluated on Total heart rate variability (HRV) (p=0.025). Auricular acupuncture significantly changed total heart rate variability (P=0.025) and ST36 stimulation decreased the low-frequency/high-frequency ratio (P=0.03) in anesthetized rats.
