The evidence has been supplied by our preceding study that electro-acupuncturing Neiguan point could ameliorate the electrical disturbance and inhibite the ATP depletion of ischemic myocardium.This study was to compare the different effect between electro-acupuncturing Tianquan and Neiguan points. The experiment was also carried out on the model of myocardial ischemia of rabbit. The methods of analysis of adenine nucleotides and detection of MAPA and MAPD50 were the same as. preceding experiments.The result showed electro-acupuncturing Tianquan point could also decrease the ATP depletion and ameliorate the electrical disturbance of ischemic myocardium

but the effect of Tiantluan was weaker than that of Neiguan point. This study indicated that the selection of acupoints in clinic has its rationale

it could be used to explain why Neiguan point is often used as the main acupoint to treat the coronary heart disease

but Tianquan point is seldom used . The study also supplied the experimental base of using meridian theory to guide the clinical practice.
