心电图运动试验中R波振幅的变化与缺血性心脏病的关系是近年来广泛讨论的一个问题。心电图运动试验,一向采用ST段压低的标准进行分析判断;这一指标对冠心病诊断的敏感性虽较高,但也存在着一定程度的假阳性和假阴性问题,。因而,可否将运动试验中R波振幅的变化作为诊断冠心病的一项辅助性指标,颇值得研究。我国自1982年起已开始注意探讨这个问题,至目前为止已对496名受试者的检测结果进行了研
The relationship between the change of R wave amplitude and ischemic heart disease in ECG exercise test has been widely discussed in recent years. ECG exercise test has always been the use of ST-segment depression criteria for analysis to determine; this indicator of coronary heart disease is more sensitive to the diagnosis, but there are also some false positives and false negatives. Therefore, the exercise test can be R wave amplitude changes as a diagnostic indicator of coronary heart disease, quite worth studying. Since 1982, China has begun to pay attention to explore this issue, so far the test results of 496 subjects have been studied
