摘要：

该文主要分析平板运动试验各项不同指标的阳性标准及诊断价值。平板运动试验是冠心病诊断和对冠心病患者运动耐力判断的一种方法。其原理是通过运动的方法增加心脏负荷，使心肌耗氧量增加，当负荷达到一定量，即超过冠状动脉供血能力时，可诱发心肌缺血，并以心电图检查结果显示出来。平板运动试验诊断冠心病的指标主要以ST段变化为主，其中又以ST段下移为主要标准。近年来，由运动试验引起的其他生理变化逐渐引入与冠心病关系的研究当中，如QRS波群改变、心率复缩环、血压变化等。平板运动试验已成为诊断冠心病及评估预后和疗效的重要手段。

Abstract:

This paper analyses the positive criteria and diagnostic value of different indices of treadmill exercise test (TET). TET is a way of diagnosing coronary heart diseases（CHD） and estimating CHD patients' exercise tolerance. The principle of TET is that exercise can increase the load of heart, which leads to increased demand for oxygen of myocardium, and when the load meets the trigger point, which means overloading the ability of supplying blood of coronary artery, myocardial ischemia occurs, which can be revealed by electrocardiogram (ECG). The indices of TET mainly focus on the change of ST segment, especially on the depression of ST segment. In recent years, the other physiological changes caused by exercise have been studied to learn the relationship between these changes and CHD, such as the changes of QRS, blood pressure and heart rate recovery loop. TET has become an important approach of diagnosing CHD and estimating prognosis and therapeutic effect.
