Key result
Acute ongoing ischemia does not cause negative T waves, which instead appear when ischemia is vanishing or in the chronic phase, and are not exclusively located in the subepicardial area.
Negative T waves in ischemic heart disease indicate vanishing or chronic ischemia, challenging the historical notion that they represent acute ongoing subepicardial ischemia.

May warrant caution interpreting negative T waves as acute ischemia; challenges historical teaching and leaves open prospective validation.
Luna et al. (2014) conducted a review in Ischemic Heart Disease. Acute ongoing ischemia does not cause negative T waves, which instead appear when ischemia is vanishing or in the chronic phase, and are not exclusively located in the subepicardial area.
