RESUMO
Objective: To observe the changes of heart rate and the contents of angiotensin Ⅱ(AngⅡ) in blood plasma in ventricular tachycardia(VT) rats with electro-acupuncture(EA) on ‘daling’(PC7). Methods: 40 SD rats were randomly divided into normal, model, treatment and control groups with 10 cases in each. VT model was duplicated by inject CsCl in femoral vein. To observe the rats’ electrocardiogram (ECG) and record their heart rates. EA was applied to‘daling’ (PC7) on treatment group and applied to‘Taiyuan’ (LU9) on control group for 5 minutes. Then, we detected the contents of AngⅡ in the rats’blood plasma respectively. Results: The heart rate and contents of AngⅡin rat increased obviously in model group were (547?30) time/min and (353.21?49.12)pg/mL). They restored to the normal state after EA ‘daling’ (PC7) are(474?25)time/min and(268.44?47.49)pg/ mL.But the effect was not obvious in ‘Taiyuan’ (LU9). Conclusion VT rat heart can be prompted to restore to the normal state after EA ‘daling’(PC7); AngⅡ played an important role in VT.
