Abstract
An evaluation of the Q-T ratio as a means of differentiating normal from abnormal tread mill stress test results was attempted. Digitalized subjects were included in the study to determine if false-positive treadmill stress test results could be identified by this means. The results indicate a lack of specificity in relying upon the Q-T ratio measurements before and after maximal treadmill stress testing. Q-T ratio, Treadmill Stress Testing.
