To differentiate proximal from peripheral right bundle-branch block, several investigators have used the right ventricular apical (RVA) activation time, but there is a lack of reference standards for infants and other children. Using intracardiac electrography, His bundle and RVA electrograms were recorded in 123 children before surgery for various types of congenital cardiac malformations. None had evidence of conduction defects on their surface ECG. The average RVA activation time was 15 +/- 7 msec (+/- SD) linearly increasing with age from infancy to adolescence. The values found in this large population may be useful as reference standards for right bundle-branch conduction times in other infants and children.
为了区分近端与远端右束支传导阻滞,一些研究者采用了右心室心尖部(RVA)激动时间,但婴儿及其他儿童缺乏参考标准。通过心内电图记录了123例各类先天性心脏畸形患儿术前的希氏束和RVA电图。所有患儿体表心电图均无传导缺陷证据。RVA平均激动时间为15±7毫秒(±标准差),从婴儿期到青春期随年龄呈线性增加。在这一大量人群中得到的值可作为其他婴儿和儿童右束支传导时间的参考标准。
