WebJul 30, 2024 · Flipped T and/or ST depression in aVL: An early sign of inferior STEMI [17] An isolated flipped T-wave and/or ST depression in aVL may be an early sign of inferior STEMI, as it can represent reciprocal changes that occur prior to ST elevation, and helps to differentiate cardiac ischemia from pericarditis. WebT wave inversion in aVL was found to be the only ECG variable significantly predicting mid segment left anterior descending artery (LAD) lesions (Odds Ratio 2.93, 95% Confidence Interval 1.59-5.37, p=0.001).
