摘　　要：目的分析左冠状动脉起源于肺动脉的心电图表现及临床诊断价值。方法回顾性分析1999年1月~2013年1月就诊的先心病患儿的心电图,其中16例左冠状动脉起源于肺动脉。结果 12例患儿在I、a VL、V 5、V 6导联出现异常Q波,9例患儿在I、aVL、V 5、V 6导联出现不同程度ST段下移、7例在I、aVL、V 5、V 6导联出现不同程度T波倒置,2例有左心室肥大的表现（合并先心病）。结论对于早期出现心衰的婴幼儿,心电图出现I、aVL、V 5、V 6导联异常Q波和ST段下移、T波倒置及合并左室扩大高度,提示左冠状动脉起源于肺动脉的可能。Objective To evalute the diagnostic value of ECG on children with anomalous origion of the left coronary artery from the pulmonary artery（ALCAPA）. Methods 12-Lead ECG was reviewed in 16 patients with ALCAPA from January 1999 to January 2013. Results Deep Q wave was found in 12 cases in leads I, aVL and V5, V6. ST segment depression with different degree was shown in 9 cases in leads I, aVL and V5, V6, and T wave inversion was found in 7 cases in the same leads, left ventricle hypertrophia was found in 2 cases. Conclusion ALCAPA should be considered when deep Q wave and ST segment depression or T wave inversion is found in I, aVL, V5, V6 leads in the children＇s ECG.
