In this paper, clinical application of isointegral analysis on body surface potential maps during ST-T segment was reviewed. ST-T integral, which was defined as the time integral value during ST-T segment, gives an important information about the abnormalities in ventricular recovery and reflects the recovery sequence. Post-exercise recording of the ST-T isointegral maps well reflects the presence and the location of myocardial ischemia in patients with 1) angina pectoris and 2) previous myocardial infarction. The combined analysis of QRST and ST-T isointegral map in left ventricular hypertrophy can determine, whether the ST-T abnormality suggests the myocardial damages or not.
本文综述了体表电位图ST - T段等积分分析的临床应用。ST - T积分定义为ST - T段的时间积分值，它提供了有关心室复极异常的重要信息，并反映复极顺序。运动后记录的ST - T等积分图能很好地反映1）心绞痛和2）既往心肌梗死患者心肌缺血的存在及部位。左心室肥厚时QRST与ST - T等积分图的联合分析可确定ST - T异常是否提示心肌损伤。
