Figure 3: Effects of EA on LVWI, HWI in rats with MH induced by ISO ( each group). MHI: myocardial hypertrophy index, LVWI: left ventricular weight index, and HWI: heart weight index. LVWIs and HWIs in the model group were significantly higher compared with the model group. EA lowered the value, and LI4 was superior to PC6. versus normal; versus model; versus PC6.
