| 摘 要： | 目的: 探讨体表心电图对小儿继发孔型房间隔缺损伴右心室肥大的诊断价值。方法: 观察183例小儿继发孔型房间隔缺损心电图,按是否伴有右心室肥大分为房间隔缺损伴右心室肥大组及房间隔缺损不伴右心室肥大组。比较8项心电图指标在2组之间的差异,分别计算其敏感度、特异度和准确度。结果: 2组患儿除心电轴右偏指标检出率差异无统计学意义(P>0.05)外,其余7项心电图指标检出率差异均有统计学意义(P<0.05～P<0.01)。心电图检查:V1导联R波峰值时间>0.03 s的敏感度为87.10%,但特异度仅为45.45%;V5 S/R>1.0的特异度为93.39%,但敏感度仅为19.35%;V1导联出现Q(q)波或R>2.0 mV、3个下壁导联均出现R波切迹、不完全性右束支传导阻滞3项指标的准确度相对较高,分别为74.32%、75.96%、71.58%,但特异度相对较低,分别为85.12%、84.30%、86.78%;以上3项联合指标的特异度为98.35%,准确度为73.77%。结论: 单项心电图指标对诊断小儿继发孔型房间隔缺损伴右心室肥大不理想,联合指标相对于单一指标效果更佳。 |

| Abstract: | Objective: To explore the value of body surface electrocardiogram(ECG) in the diagnosis of secundum atrial septal defect complicated with right ventricular hypertrophy in children.Methods: The ECG of 183 children with secundum atrial septal defect were observed.All cases were divided into the secundum atrial septal defects complicated with right ventricular hypertrophy group and without right ventricular hypertrophy.The 8 indexes of ECG between two groups were compared,the sensitivity,specificity and accuracy rate of whose were calculated,respectively.Results: Between two groups,the difference of the detection rate of ECG shaft starboard was not statistically significant(P>0.05),but the differences of the detection rates of other 7 electrocardiographic indexes were statistically significant(P<0.05 to P<0.01).The results of ECG showed the sensitivities and specificities of VATV1>0.03 s and V5 S/R>1.0 were 87.10% & 45.45% and 93.39% &19.35%,respectively.The Q(q) wave in lead V1 or R>2.0 mV and notched on R wave in three inferior leads and incomplete right bundle branch block were found,the accuracy rates of whose were 74.32%,75.96% and 71.58%,but their specificities were 85.12%,84.30% and 86.78%,respectively.The specificity and accuracy rate of 3 joint indexes were 98.35% and 73.77%,respectively.Conclusions: The diagnostic effect of a single index of ECG on secundum atrial septal defect complicated with right ventricular hypertrophy is not ideal,the diagnostic effect of joint index is better. |
