[Effect of electroacupuncture point on the value of ventricular fibrillation threshold in rats]

The Neiguan and Lingdao were stimulated by electroacupuncture in anesthetized Wistar rats. We observed that the value of ventricular fibrillation threshold (VFT) was increased significantly in 30 min of electro-acupuncturing (P less than 0.01) and in 15 min of stopping the acupuncturing (P less than 0.05). Although the value of VFT was increased until 30 min of stopping acupuncture, it was not significantly different compared with its basic value. The control group were dealt with the same way as the experimental group except electroacupuncture. The value of VFT measured in control group were not significantly different compared with its basic value.
