Description

Previously we reported that acupuncture to the stellate ganglion stimulates sympathetic nervous system while it decreases heart rate.<br>As it is said that R-R intervals in electrocardiogram (ECG) reflect functions of parasympathetic nervous system, we measured effects of electrical acupuncture to the stellate ganglion (SG) or traditional acupuncture points (AP) on the meridians (H7: SHENMEN and P4: HSIMEN) on R-R intervals in ECG by using 24 patients; 12 each in SG-group and AP-group.<br>Results are as follows; (1) Means of heart rate (HR) decreased with 1-3bpm in the both groups; (2) Coefficients of variation (CV) of HR increased with 1-2% in the both groups; (3) Means of R-R intervals prolonged with 39-47msec in the SG-group and 20-44msec in the AP-group, respectively; (4) CV of R-R intervals increased with 1% in the SG-group only.<br>It is suggested that acupuncture stimulates not only sympathetic nervous system, but also parasympathetic nervous system.
