[摘要] 目的 探討運動平板試驗心電圖變化與冠狀動脈病變部位的相關性，以指導臨床治療。 方法 回顧性分析50例行運動平板試驗及冠狀動脈造影檢查的冠心病患者的臨床治療，根據冠狀動脈造影檢查所得主要病變血管將患者分為右冠組11例、左前降支組21例及回旋支組18例，分別對三組患者運動平板試驗所得結果進行分析，對比各組患者運動平板試驗中ST段改變導聯的差異。 結果 右冠組：下壁導聯（Ⅱ、Ⅲ、avF）ST段改變者明顯高於其他導聯ST段改變者；左前降支組：前壁導聯（V4-V6）ST段改變者明顯高於其他導聯ST段改變者；而回旋支組各導聯ST段改變者未見統計學差異。三組間比較，ST段改變導聯存在統計學差異。結論 運動平板試驗的心電圖可對冠狀動脈病變進行大致定位，臨床可參考治療。

[Abstract] Objective To explore the relationship between electrocardiogram treadmill exercise test and coronary lesion site,and to guide the clinical treatment. Methods A total of50 cases with heart coronary disease were chosen to take treadmill exercise test. All these patients were divided into 3 groups.11 cases were in the right coronary group.21 cases were in the left anterior descending branch group.18 cases were in the left circumflex group. Compared the treadmill exercise test results of these 3 groups,and to compare the exercise treadmill test in patients with contrast group ST segment changes lead difference. Results The inferior (II, III, avF) ST segment changes of right coronary group were significantly higher than those of other lead ST segment changes.The lead (V4-V6) ST segment changes of left anterior descending branch of the anterior wall of group were significantly higher than those of other lead ST segment changes.The lead ST segment changes LCX group were _disibledevent=4.747， P ＞0.05）
