Treadmill tests were performed in one hundred men below 60, with computerized assessment of their ECG data. Reduced R wave amplitude from lead V5 at maximum exercise was only noted in subjects showing no electrocardiographic evidence of ischemia. Increased R wave from lead V5 was regarded as cardiac dysfunction in response to exercise, which, in the presence of ischemic ECG changes, preceded the development of pathologic ST depression. A negative T wave from leads III and aVF on resting ECG did not correlate with abnormal exercise test results. Ventricular arrhythmias were more common in subjects with non-ischemic ECG changes during exercise.
对100名60岁以下男性进行了跑步机测试，并对他们的心电图数据进行了计算机化评估。仅在未显示心电图缺血证据的受试者中，观察到最大运动时V5导联R波振幅降低。V5导联R波增加被视为运动引起的心脏功能障碍，在存在缺血性心电图改变的情况下，其先于病理性ST段压低的出现。静息心电图III导联和aVF导联T波倒置与异常运动试验结果无关。运动期间心电图无缺血性改变的受试者室性心律失常更为常见。
