Twenty-one patients with electrocardiographically diagnosed left ventricular hypertrophy (LVH) and essentially normal coronary arteries on arteriography were subjected to a snbmaximal treadmill stress test (TST). Six of the 16 patients (38 percent) able to attain a heart rate of at least 90 percent of their predicted maximum were found to have positive tests. It is concluded that LVH in and of itself may cause a positive TST.
