Pilot Study of Acupuncture Point Laterality: Evidence from Heart Rate Variability

Figure 3

Frequency domain results. LS: left Neiguan acupoint was stimulated; RS: right Neiguan acupoint was stimulated; LF: low frequency; HF: high frequency; n.u.: normalized unit; LF/HF: low frequency high frequency ratio; PSD: Power spectrum density. Data are expressed as Mean ± SD; *𝑃<0.05; LS group versus RS group; one-sample paired 𝑡-test.
