【摘要】 我们以前的研究证明电针内关穴明显改善缺血心肌的电紊乱，同时抑制ATP的耗竭。本研究旨在比较电针心包经天泉穴与内关穴的作用有无差异。实验仍以家兔心肌缺血为模型，分析缺血心肌腺苷酸的同时仍附以单相动作电位的二项指标（MAPA和MAPD50）作比较观察。方法均与以前相同，只加入外天泉穴以兹比较。结果表明：电针天泉穴也能降低缺血心肌ATP的耗竭程度和改善电紊乱现象，但其效果不如针内关穴作用强。此现象反映了临床实践中选穴的合理性，临床治疗冠心病内关是主穴，而天泉穴很少选用。更多还原

【Abstract】 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.更多还原
