Exercise testing (ET) stands as one of the most easy, affordable, cost effective, non invasive methods for diagnosing coronary heart disease. Its sensitivity, specificity and prognostic value, especially in the prime era of its implementation in the cardiac diagnostic procedure, is relatively limited. Novel exercise criteria and indices based either on ST segment changes or ST segment independent parameters, such as "Athens QRS score", have greatly improved the diagnostic ability and accuracy of ET. Complex ECG-derived indices linked to ST changes along with the use of right-sided precordial leads have also enhanced the diagnostic accuracy of ET with respect to the extent of ischemic heart disease and the detection of specific culprit vessels. ET contains also a prognostic value, since several ET-derived parameters have been associated with adverse outcome, including ST changes, blood pressure and heart rate response to exercise and duration of exercise.
运动试验（ET）是诊断冠心病最简便、经济、有效的非侵入性方法之一。其敏感性、特异性和预后价值，尤其是在其在心脏诊断程序中的应用初期，相对有限。基于 ST 段变化或 ST 段独立参数的新型运动标准和指标，如“雅典 QRS 评分”，极大地提高了 ET 的诊断能力和准确性。与 ST 变化相关的复杂 ECG 衍生指标以及右侧胸前导联的使用也提高了 ET 对缺血性心脏病程度和特定罪犯血管检测的诊断准确性。ET 还具有预后价值，因为一些 ET 衍生参数与不良预后相关，包括 ST 变化、运动时血压和心率反应以及运动持续时间。
