The T wave in leads II, V4, and V6 in the electrocardiograms of 1,401 consecutively entering 18-year-old male conscripts at a military processing center in 1975 were classified, and the relationship between the frequency of the T-wave changes relative to the psychosocial and medical data of the subjects was examined. One percent of the conscripts had a negative T in one or more of these leads, and twelve percent showed some deviation from the "normal T," usually a T wave of less than ten percent of the R-wave amplitude. A common finding was the presence of a "notch" in the T wave of lad V4 (a negative deflection in the middle of a positive T wave). Those with T-wave changes showed the same incidence of signs and history of heart disease as those with a normal T. However, those with an abnormal T showed higher heart rate and systolic blood pressure at rest. Further, they had more nervous symptoms and a higher consumption of alcohol and tranquilizers. These findings were as common in the larger group of flat T waves as in the smaller group with T-wave changes of the type normally attributed to organic heart disease (i.e., having notched, or more or less inverted T waves without ST depression). The maximal work capacity and vital capacity were slightly lower in subjects with abnormal T waves. However, this was fully explained by lesser height. It is suggested that in the majority of these cases, T-wave changes in young adults are due to increased sympathetic tone rather than to organic heart disease.
对1975年在一个军事处理中心连续入伍的1401名18岁男性新兵的心电图中II、V4和V6导联的T波进行了分类，并研究了T波变化频率与受试者心理社会和医学数据之间的关系。1%的新兵在这些导联中的一个或多个导联出现T波倒置，12%的新兵T波与“正常T波”有一定偏差，通常是T波振幅小于R波振幅的10%。一个常见的发现是V4导联T波出现“切迹”（正向T波中间的负向偏转）。T波改变者心脏病体征和病史的发生率与T波正常者相同。然而，T波异常者静息时心率和收缩压较高。此外，他们有更多的神经症状，酒精和镇静剂的消耗量也更高。这些发现在较大的平坦T波组和较小的通常归因于器质性心脏病的T波改变组（即有切迹或或多或少倒置的T波且无ST段压低）中同样常见。T波异常的受试者最大工作能力和肺活量略低。然而，这完全可以用身高较低来解释。有人认为，在大多数情况下，年轻人的T波改变是由于交感神经张力增加，而非器质性心脏病所致。
