Body surface isopotential maps were compared between 52 normal children and 47 normal adults. While sequential changes in body surface potential distribution were similar, 4 significant differences in body surface maps were observed between them: 1) Surface maps of normal children showed less smooth contour of isopotential lines than did those of normal adults. For example, breakthrough minimum was recognized more frequently in children (100%) than adults (65%). 2) Breakthrough minimum appeared earlier in normal children (23.2 +/- 5.0 msec) than in normal adults (29.2 +/- 4.3 msec), and more leftwards on the chest. 3) Forty-seven percent of the children showed positive potentials on the upper and right portions of the anterior chest in the terminal phase of QRS, but this pattern was not observed in normal adults. 4) The maximum at the time of the peak of the T wave appeared more leftward in normal children than normal adults.
对52名正常儿童和47名正常成年人的体表等电位图进行了比较。虽然体表电位分布的顺序变化相似，但在他们之间观察到体表图有4个显著差异：1）正常儿童的体表图等电位线轮廓不如正常成年人的平滑。例如，儿童（100%）比成年人（65%）更频繁地识别出突破最小值。2）正常儿童突破最小值出现的时间（23.2±5.0毫秒）比正常成年人（29.2±4.3毫秒）更早，且在胸部更靠左。3）47%的儿童在QRS终末阶段前胸上部和右侧出现正电位，但正常成年人未观察到这种模式。4）正常儿童T波峰值时的最大值比正常成年人更靠左。
