ObjectiveTo observe the synergetic protective effect of electro-acupuncturing(EA) PC6 and BL15 on improving the heart rate variability(HRV) parameters in acute myocardial ischemia in rats.Methods40 rats were randomly divided into 5 groups,namely control group,model group,PC6 group that treated with EA at PC6 acupoint,BL15 group that treated with EA at BL15 acupoint,PC6 add BL15 group that treated with EA at both PC6 and BL15 acupoints.Injecting pituitrin into sublingual vein simulated the acute ischemic rat...
