BACKGROUND AND PURPOSE
The electrocardiogram (ECG) is commonly used as a screening tool for diagnosis of the ostium secundum atrial septal defect (ASD). We sought to analyze the utility of conventional ECG criteria in detecting right ventricular enlargement (RVE) due to the presence of an ASD.
METHODS
Patients who underwent transcatheter or surgical closure of an isolated ASD between 1997 and 2004 were included if an ECG was performed less than 9 months before ASD closure and had echocardiographic RVE.
RESULTS
Of 99 children (aged 6.8 +/- 4.7 years; range, 1-18 years) with RVE and ASD, 57% had an ECG that met 1 or more RVE criteria. The sensitivity of ECG increased to 70% in younger patients and to 80% for the largest defects.
CONCLUSIONS
Electrocardiographic criteria for RVE are present in just more than over half of young patients with large ASDs. Although ECG is more sensitive in younger patients, it is unreliable as a screen for this lesion.
背景与目的
心电图（ECG）通常用作筛查工具，以诊断继发孔型房间隔缺损（ASD）。我们试图分析传统心电图标准在检测因ASD存在而导致的右心室扩大（RVE）方面的效用。
方法
纳入1997年至2004年间接受经导管或手术闭合孤立性ASD的患者，条件是在ASD闭合前不到9个月进行了心电图检查且有超声心动图显示的RVE。
结果
在99例患有RVE和ASD的儿童（年龄6.8±4.7岁；范围1 - 18岁）中，57%的患者心电图符合1项或更多RVE标准。心电图在较年轻患者中的敏感性增至70%，对于最大的缺损增至80%。
结论
超过半数患有大ASD的年轻患者存在RVE的心电图标准。尽管心电图在较年轻患者中更敏感，但作为该病变的筛查手段并不可靠。
