摘　　要：目的了解心电图下壁导联Crochetage R波切迹在继发孔型房间隔缺损(ASD)检测中的应用价值。方法回顾性分析110名继发型ASD患者的心电图(ASD组),并以同期超声心动图正常无心脏疾患的110名健康体检者(对照组)作对照,比较Crochetage R波切迹在两组心电图中的分布特点;分析ASD缺损大小与Crochetage R波切迹检出率的关系。结果ASD组出现Crochetage R波切迹的几率明显高于对照组(63.6%vs 10.9%,P<0.01)。ASD患者缺损直径0~5、6~10、>10 mm分别有41、45、24例,出现Crochetage R波切迹分别有18、30、22例;随着缺损直径的增大,出现Crochetage R波切迹的几率也增高(P<0.01)。结论心电图下壁导联Crochetage R波切迹似可作为检测ASD的辅助指标。Objective To explore the value of Crochetage(Notch)on R wave in the inferior leads of electrocardiogram(ECG)in the diagnosis of secundum trial septal defect(ASD).Methods A retrospective analysis was conducted on the ECGs of 110 patients with secundum ASD(ASD Group).Taking 110 healthy subjects(Control Group)with normal echocardiography and no heart disease at the same period as control,the distribution characteristics of Crochetage(Notch)on R wave in the ECGs of both groups were compared,and the influence of ASD defect size on the detection rate of Crochetage(Notch)on R wave was analyzed.Results The ASD Group had a higher incidence in Crochetage(Notch)on R wave compared with the Control Group(63.6%vs 10.9%,P<0.01).There were 41,45 and 24 ASD patients with a defect diameter of 0~5,6~10 and>10 mm,respectively,of which 18,30 and 22 cases had Crochetage(Notch)on R wave.The incidence of Crochetage(Notch)on R wave increased with the increase of defect diameter(P<0.01).Conclusion The Crochetage(Notch)on R wave in the inferior leads of electrocardiogram may serve as a supplementary indicator for ASD detection.
