Exercise testing has changed dramatically in scope over the past 50 years. While initially used to assess functional capacity, it is now also utilized to detect the presence and severity of coronary artery disease (CAD), to evaluate postmyocardial infarction patients at risk for future cardiac events, to screen certain asymptomatic populations for CAD, and to evaluate dysrhythmias, peripheral vascular disease, and lung disease. Dynamic exercise in continuous multistage protocols is most popularly employed because of the more easily measured workload. The safety of exercise testing, its contraindications and termination end points are summarized. The sensitivity of exercise testing ranges between 60 and 70% while specificity has been reported between 85 and 90%. Both sensitivity and specificity are enhanced through use of radionuclide exercise thallium imaging and ventricular angiography.
在过去50年里，运动试验的范围发生了巨大变化。虽然最初用于评估功能能力，但现在它也被用于检测冠状动脉疾病（CAD）的存在和严重程度，评估心肌梗死后有未来心脏事件风险的患者，筛查某些无症状人群的CAD，以及评估心律失常、外周血管疾病和肺部疾病。由于工作量更容易测量，连续多阶段方案中的动态运动最常被采用。总结了运动试验的安全性、其禁忌症和终止终点。运动试验的敏感性在60%至70%之间，而特异性据报道在85%至90%之间。通过使用放射性核素运动铊成像和心室造影，敏感性和特异性都得到了提高。
