Eighteen-seven unipolar ECGs were simultaneously recorded from the entire thorax in 61 patients having negative T waves and 44 normal male volunteers. We measured a recovery time, which was defined as an instant of maximal derivative of the T wave as the index of local recovery. Significant correlations were observed between the recovery time and each of T wave parameters (positive T wave amplitude, negative T wave amplitude, and T integral). The T wave parameters were dependent on recovery times. Body surface recovery time distributions clearly separate anterior myocardial infarction and left ventricular hypertrophy. Appearance of the negative T waves correlates well with the presence of the area with delayed recovery time on the spatial distribution.
在61例T波倒置患者和44名正常男性志愿者中,同时从整个胸部记录了187份单极心电图。我们测量了一个恢复时间,其定义为T波最大导数瞬间,作为局部恢复的指标。观察到恢复时间与每个T波参数(正向T波振幅、负向T波振幅和T积分)之间存在显著相关性。T波参数取决于恢复时间。体表恢复时间分布能清晰区分前壁心肌梗死和左心室肥厚。负向T波的出现与空间分布上恢复时间延迟区域的存在密切相关。
