ABSTRACT
Objective To observe the real-time effect of retaining needle at Lingtai (GV 10) and Shendao (GV 11) on ST-T segment on cardiogram in patients with angina pectoris of coronary heart disease (CHD).Method Thirty patients with angina pectoris of CHD who received acupuncture at Lingtai (GV 10) and Shendao (GV 11) were divided into group A with needles retained after insertion of the needles and group B without needles retained. The two groups were observed by using 12-lead electrocardiogram (ECG) before and after treatment, to compare the ST segment and T wave atⅡ,Ⅲ, avF lead and V4, V5, V6lead before and after treatment.Result After treatment, ST segment atⅡ,Ⅲ, avF lead and V4, V5, V6lead was changed significantly in group A (P<0.05). T wave was significantly changed atⅡ,Ⅲ, avF lead after treatment in group A (P<0.05). T wave at V4, V5, V6 lead was significantly changed after treatment in both groups (P<0.01,P<0.05).Conclusion Acupuncture at Lingtai (GV 10) and Shendao (GV 11) can improve myocardial ischemia in angina pectoris of CHD; compared to acupuncture without needles retained, retaining needles after acupuncture can produce a more significant effect in improving the inferior and anterior myocardial walls and a better real-time effect on ST-T on ECG of angina pectoris of CHD.
