How often do you see an ECG that is just a little off? Maybe the T wave is flat, oddly-shaped or inverted. Maybe the ST segment is coved, very minimally-depressed or shows some J point elevation.

Diffuse T wave inversion is stage III of the ECG changes ... A posterior wall MI shows ST depression, not elevation in leads V1 and V2 with an R:S ratio greater that 1 in lead V1.
