心电图运动试验是诊断和鉴别冠心病的一个有价值的非侵入性手段。多年来,ST段移位被认为是运动诱发心肌缺血的有力证明,并一直作为运动试验阳性的判断标准。遗憾的是ST 段移位也可见于非冠心病的其他器质性心脏病,而且运动试验引起的ST段移位对进行流行病学调查和鉴别是否有冠心病是非常困难的。由于运动试验中单
ECG exercise test is a valuable non-invasive means of diagnosis and differential diagnosis of coronary heart disease. Over the years, ST-segment shift has been shown to be a strong evidence of exercise-induced myocardial ischemia and has been used as a test for the positiveness of exercise tests. Unfortunately, ST segment displacement can also be seen in other organic heart disease without coronary heart disease, and exercise-induced ST segment displacement for epidemiological investigation and to identify whether there is coronary heart disease is very difficult. Due to exercise test alone
