多年来,心脏科医生为仅有少许或没有冠心病症状者以及健康人出现运动试验心电图异常而感到困惑。迄近,对所谓的“隐型冠心病”还不能提出充分的解释。随着冠状动脉造影的发展,发现冠状动脉完全正常的患者也会出现缺血型ST段压低和假阳性运动试验反应。鉴于当前有许多患者都做过运动试验和冠状动脉造影,故可以对运动心电图的价值进行适当的评价。运动心电图的诊断价值任一诊断试验最常根据其敏感性(Sens)和特异性(Spec)来评价其价值。敏感性系冠心病患者中试验异常者的比率。特异性是冠
Over the years, cardiologists have been confused by the electrocardiographic abnormalities of exercise tests in individuals with or without symptoms of coronary heart disease and in healthy individuals. So far, the so-called “hidden coronary heart disease” can not be fully explained. With the development of coronary angiography, ischemic ST-segment depression and false-positive exercise tests have also been found in patients with normal coronary arteries. Given that many patients currently have exercise tests and coronary angiography, the value of exercise ECG can be appropriately evaluated. Diagnostic Value of Exercise ECGs The most often diagnostic value of any diagnostic test is its Sensitivity and Spec. Sensitivity of coronary heart disease in patients with abnormal test rate. Specificity is crown
