Observation Of The Immediate Effect To The ST-T Segment On EKG By Retaining Needles Or Not On "Lingtai" And "Shendao" Points In Coronary Heart Disease

Objective: This study is to observe and compare the immediate effect of the ST-T segment on EKG in coronary heart disease by acupuncturing lingtai and shendao points by retaining needles or not,and to certify that retaining needles whether has the superior amelioration effect for CHD.Method: In order to reduce error, the open-controlled study was selected.30 coronary heart disease(CHD) patients were divided by means of random number table into retaining-needles group and not-retaining-needles group. The changes of immediate effect of ST-T segments inⅡ,Ⅲ,avF leads and V4,V5,V6 leads of each group were observed before and 10mins after the treatment. In order to avoid the errors from additive and delaying effect, both observations should be 7 days apart.Results: The ST segment inⅡ,Ⅲ,avF leads of not-retaining-needles groups had no significant differences before and after treatment(P>0.05), but retaining-needles group had a significant difference(P<0.05). The T waves inⅡ,Ⅲ,avF leads of not-retaining-needles group had no significant differences before and after treatment, but retaining-needles group had a significant difference(P<0.05). The ST-T segment in V4,V5,V6 leads of both groups had a significant difference before and after treatment (P<0.05).The difference value between groups of the ST-T segment in V4,V5,V6 leads had a significant difference (P<0.05). The T wave in V4,V5,V6 leads of both groups had a significant difference before and after treatment (P<0.05). The difference value of T waves in V4,V5,V6 leads between groups had a significant difference (P<0.05).Conclusion: Acupuncturing"lingtai"and"shendao"points, retaining needles or not, can both ameliorate the ischemia state of angina pectoris in CHD. The retaining-needles group is superior to the not-retaing-needles group on the amelioration for cardiac muscles of inferior and lateral heart wall. The retaining-needles group has the superior amelioration for the immediate effect of EKG angina pectoris in CHD.
