摘　　要：目的观察平板运动试验（TET）诱发不同导联ST段压低患者的冠状动脉病变部位及病变数目,探讨其相关性。方法选取TET阳性同时经冠脉造影检查明确诊断为冠心病患者56例为研究对象,分析临床资料、TET参数,探讨不同导联ST段压低与冠状动脉病变部位及病变数目的相关性。结果冠脉造影阳性同时TET阳性患者大多存在冠心病危险因素及典型心绞痛症状（94.6%）。经Logistic回归分析发现V4--V6导联,Ⅱ、Ⅲ、a VF＋V4~V6导联及Ⅱ、Ⅲ、a VF＋Ⅰ、a VL或V2、V3导联ST段压低患者发生前降支病变的风险较高,但是并未发现不同导联ST段压低与冠脉病变部位及病变数目存在相关性（P〉0.05）。结论 TET诱发不同导联ST段压低与冠脉病变部位及病变数目无相关性。Objective To explore the correlation between different leads of ST segment depression and position of coronary lesions in patients with exercise-induced ST segment depression. Methods A total of 56 patients who showed ST segment depression in treadmill exercise test（TET） and diagnosed significant coronary stenosis by coronary angiography in this study.Clinical characteristics and TET parameters were recorded.Logistic regression analysis was performed to identify the correlation between different leads of ST segment depression and position of coronary lesions. Results Risk factors（age, gender, hypertension, diabetes mellitus, dyslipidaemia, smoking, obesity） and typical chest pain （94.6%） were present in most patients. Logistic regression analysis showed that ST segment depression in Ⅱ、Ⅲ、,aVF＋V4--, Ⅱ、Ⅲ、,aVF＋ Ⅰ VL or V2,V3, had a high risk to predict left anterior deseedding artery,but hardly reflected the position or pathological amout of coronary artery （ P〉0.05 ） . Conclusion Exercise-induced ST segment depression in different leads hardly reflects the position or pathological amout of coronary artery.
