Using a system for obtaining body surface potential distributions from 150 sites on the anterior and posterior torso, 43 body surface maps were evaluated in 31 normal infants, ages 15 hours to 10 months. Serial maps were obtained at 0.6-msec intervals during QRS and at 2.4-4-msec intervals throughout the ST-T wave. We found an orderly evolution of both QRS and ST-T wave maps during the first year of life. In the newborn, the patterns during the latter half of QRS were consistent with early completion of depolarization of the left ventricle and prolonged depolarization of the right ventricle. The patterns changed gradually such that by 5-6 months of age, the maps demonstrated simultaneous effects of both right and left ventricles during the latter half of QRS. By 9 months, the QRS patterns were similar to those of older children and adults. The changes in the ST-T-wave maps were consistent with the idea that age-related changes in the sequence of ventricular activation.
使用一个从躯干前后150个部位获取体表电位分布的系统，对31名年龄在15小时至10个月的正常婴儿的43幅体表图谱进行了评估。在QRS期间以0.6毫秒的间隔以及在整个ST - T波期间以2.4 - 4毫秒的间隔获取连续图谱。我们发现，在生命的第一年中，QRS和ST - T波图谱都有一个有序的演变过程。在新生儿中，QRS后半期的模式与左心室早期去极化完成以及右心室去极化延长一致。这些模式逐渐改变，以至于到5 - 6个月大时，图谱显示在QRS后半期左右心室同时起作用。到9个月时，QRS模式与较大儿童和成人的模式相似。ST - T波图谱的变化与心室激活顺序随年龄变化的观点一致。
