The T wave is most often concordant with the QRS wave because the T-wave axis is normally within 45 degrees of the QRS axis in adults. ... ST depression is minimal and downsloping, running into the gradual descent of the inverted T wave.

Consider this example. The QRS complexes are very small in the inferior leads so our threshold for what constitutes a significant amount of ST-elevation is less. This is known as the rule of proportionality. Because the ST-segment elevation is < 1 mm the computer ...
WebST-T changes: V1-V2 shows downsloping ST-segments and inverted T-waves. Leads V5, V6, I and aVL shows positive T-waves. If the QRS duration is ≥0,110 seconds but <0,12 seconds, the right bundle branch block is said to be incomplete.
