Abstract

A 63-year-old male patient with inferior infarction revealed transient attenuation of the Q-waves in II, III, and aVF, and R-waves in V1-V3 during an exercise stress test. Myocardial scintigraphy disclosed ischemia of the anterior wall and coronary arteriography, a 90% stenosis of the left main coronary artery (LMCA). The mechanism involved appears to be a transient failure of the anterior wall to generate adequate depolarization forces for the genesis of Q-waves in the inferior leads and R-waves in the anterior leads. This electrocardiogram sign is diagnostic of severe anterior wall ischemia due to left anterior descending or LMCA stenosis.
