Abstract：Objective To evaluate the application value of electrocardiogram(ECG) in diagnosing anomalous origin of left coronary artery from pulmonary artery(ALCAPA). Methods Sixteen ALCAPA patients were enrolled in our study who had admitted in Wuhan Asia Heart Hospital from December 2004 to September 2016. They were diagnosed with ALCAPA by dual source computed tomography and confirmed by surgery. Theses patients were classified into group A(<12 months, 4 cases) and group B(>12 months, 12 cases), and their clinical manifestations and ECG features were analyzed. Results Crying and hard sucking were mainly observed among infants in group A while chest pain and backache were primary symptoms of group B. Patients in both of the two groups could be heard cardiac souffle in the apex of heart and between the fourth rib of the edge of left sternum. The incidences of abnormal Q wave and ST-T change in lead Ⅰ and aVL were both high in the two groups, with no statistically significant differences(P>0.05). However, the incidence of T wave inversion in lead V5and V6 in group A was significantly higher than that in group B, with statistically significant difference(P<0.05). Conclusion ECG of ALCAPA is characterized by abnormal Q wave complicating ST-T changes in lead Ⅰ and aVL. T wave inversion in lead V5 and V6 indicates serious myocardial ischemia among infants under 12 months. A combination of characteristic changes of ECG and physical examination is helpful for the diagnosis of ALCAPA.
