摘　　要：目的:探讨下壁导联钩型R波在鉴别小儿继发孔型房间隔缺损(ASD)伴右心室肥大者是否同时伴有肺动脉高压中的作用。方法:从3个下壁导联出现钩型R波和传统的诊断右心室肥大的心电图指标来比较58例ASD伴右心室肥大同时伴肺动脉高压(A组)与74例ASD伴右心室肥大不伴肺动脉高压(B组)的心电图。结果:3个下壁导联均出现钩型R波,A组出现率明显高于B组(P<0.01);而传统右心室肥大心电图诊断指标的出现率2组差异均无统计学意义(P>0.05)。结论:钩型R波不但有助于诊断ASD,还是鉴别小儿ASD伴右心室肥大是否同时伴肺动脉高压的良好指标。Objective： To investigate the effect of crochetage on R wave on identification of secundum atrial septal defect with right ventricular enlargement whether accompanied with pulmonary arterial hypertension at the same time. Methods： According to 3 inferior leads appeared with crochetage on R wave and the traditional electrocardiogram diagnostic standard for right ventricular enlargement,58 atrial septal defect cases with right ventricular enlargement also with pulmonary arterial hypertension（ group A） and 74 atrial septal defect cases with right ventricular enlargement without pulmonary arterial hypertension（ group B） were compared. Results： The emergence rate of 3 inferior leads appeared with crochetage on R wave in group A were higher than in group B（ P〈0. 01）; but about the traditional electrocardiogram diagnostic standard for right ventricular enlargement,there were no statistical difference between the two groups（ P 〉0. 05）. Conclusions： Crochetage on R wave in inferior limb leads can not only be used as an independent electrocardiogram signs for diagnosing atrial septal defect,but also be used as a good index of identifing pediatric atrial septal defect with right ventricular enlargement also with pulmonary arterial hypertension at the same time.
