Comparison of the Therapeutic Effects of Acupuncture at PC6 and ST36 for Chronic Myocardial Ischemia

Figure 2

Examples of lead II and leads V₁–V₃ ECG of the PC6 and ST36 groups minipigs before (baseline) and after the operation and after needle-embedding (NE) and electroacupuncture (EA). (a)-(b) Examples of lead II ECG of the PC6 and ST36 groups before (baseline) and after operation, after NE, and after EA. It showed that the ST segment declined and T wave became bidirectional after operation. After acupuncture, ST segment came back to basic line, T wave became upward, and the QT interval prolonged significantly after acupuncture at PC6 and ST36. (c)-(d) Examples of leads V₁–V₃ ECG of the PC6 and ST36 groups before (baseline) and after operation and after EA. It showed that the pathologic Q wave appeared at lead V₁–V₃ at the 4th week after the operation, and the pathologic Q wave disappeared at leads V₂ and V₃ after acupuncture at PC6 and ST36.
