A quantification of the Frank and McFee-Parungao orthogonal electrocardiogram of 175 normal children, ages 2-10 years is presented. There are significant differences in age groups 2-5 and 6-10. The QRS voltages of the younger group demonstrate 1) greater Z anterior, 2) greater initial X right, 3) greater terminal X right, 4) smaller Y inferior, and 5) the T vector is oriented more posteriorly. There are significant differences between the two lead systems. 1) Frank spatial voltages are 70% of those of McFee. 2) Frank X left is 70% of McFee, but terminal X right is 75% and initial X right is 60% of McFee. 3) Frank Y inferior is 78% of McFee, but initial Y superior is 83% and terminal Y superior 61% of McFee. 4) Frank Z anterior is 64% and Frank Z posterior is 70% of McFee. 5) In terms of ratios the Frank is relatively less inferior, about equally posterior and more terminally right. 6) The T vector is more posterior in Frank than McFee.
本文给出了175名年龄在2至10岁的正常儿童的弗兰克（Frank）心电图和麦克菲 - 帕伦高（McFee-Parungao）正交心电图的量化结果。2至5岁年龄组和6至10岁年龄组之间存在显著差异。较年幼组的QRS电压表现为：1）Z前向电压更高；2）初始X右向电压更高；3）终末X右向电压更高；4）Y下向电压更低；5）T向量更向后。两种导联系统之间存在显著差异：1）弗兰克空间电压为麦克菲电压的70%；2）弗兰克X左向电压为麦克菲的70%，但终末X右向电压为麦克菲的75%，初始X右向电压为麦克菲的60%；3）弗兰克Y下向电压为麦克菲的78%，但初始Y上向电压为麦克菲的83%，终末Y上向电压为麦克菲的61%；4）弗兰克Z前向电压为麦克菲的64%，弗兰克Z后向电压为麦克菲的70%；5）就比例而言，弗兰克导联相对下向程度较小，后向程度大致相同，终末右向程度更大；6）弗兰克导联中的T向量比麦克菲导联中的更向后。
