OBJECTIVE: To observe the effect of low-frequency or high-frequency electroacupuncture (EA) stimulation of "Neiguan" (PC 6) on changes of skin blood perfusion volume of heart-related and heart-irrelevant acupoints in rats with normal or ischemic myocardium. METHODS: =8 in each group). The myocardial ischemic (MI) model was established by occlusion of the anterior descending branch of the left coronary artery. 2 Hz and 100 Hz EA was respectively applied to left PC 6 for 20 min, once daily, a total of three times. Electrocardiogram (ECG) was recorded after the last treatment. Serum cardiac troponin T (cTnT) contents were assayed by ELISA. The skin blood perfusion volumes of bilateral PC 6, "Zusanli" (ST 36) and "Yanglingquan" (GB 34) were observed by laser speckle contrast imaging. RESULTS: <0.05). CONCLUSIONS: Skin blood perfusion volumes around PC 6 and ST 36 can specifically reflect the change of the myocardial state.
