Significance of precordial T-wave increase during treadmill stress testing

It appears that a T-wave amplitude increase of ≥2.5 mm in lead V2 during a treadmill stress test may be specific (95%), even though this finding only occurs occasionally. Therefore, a T-wave amplitude increase during an exercise test may aid in the diagnosis of the few patients who develop this abnormality, especially if there is no ST depression, as has occurred during several recent exercise tests.
