In addition to 'Electrocardiogram T wave amplitude decreased', there may be other similar symptoms or signs that better match your side effect. These have also been listed below for your convenience.

Another way to describe this would be that the ST segment elevation is less than 25% of the T wave amplitude in early repolarization. The ST segment elevation in early repolarization resolves when ...

U wave that occurs just after the T wave and is usually of smaller amplitude than the T wave. Flattening of the T wave. ST depression on occasion, which can mimic ischemia.
