81名平均年龄58岁的疑似下肢动脉疾病的连续患者接受了标准的5分钟跑步机跛行测试。在测试之前、期间和之后，对患者进行心电图监测。在81例接受研究的患者中观察到的心电图异常数量从静息时的33例（40.6%）增加到运动时的49例（60.5%）。运动中最常见的异常是阵发性心搏和ST-T波变化的发生率和增加，在某些情况下，这些变化会危及生命，导致试验中止。由于跛行患者的主要危险似乎来自心脏病死亡率和发病率的增加，而不是肢体循环受损的后果，因此强烈建议在跑步机跛行试验期间进行心电图监测，尽管实践很少。
Eighty-one consecutive patients of an average age of 58 years with suspected lower limb arterial disease underwent standard 5-minute treadmill claudication testing. Prior to, during, and after testing the patients were monitored electrocardiographically. The number of electrocardiographic abnormalities seen in 81 patients undergoing study increased from 33 (40.6%) at rest to 49 (60.5%) with exercise. The commonest abnormalities encountered with exercise were the development and increased incidence of paroxysmal beats and ST-T wave changes which, in some instances, became life-threatening, aborting the test. Since the principal hazard for patients with claudication appears to derive from an increase propensity to cardiac mortality and morbidity, rather than from the consequences of impaired circulation to the limb, electrocardiographic monitoring during treadmill claudication testing, though little practiced, is strongly advised.
