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.
