(A) Delayed 12-lead electrocardiogram, with ST-segment elevation in V3-V6. (B) Cardiac magnetic resonance imaging 4-chamber slice utilizing fluid-sensitive sequence (TIRM—turbo inversion recovery magnitude) demonstrating high signal (relative to skeletal muscle) within the mid to apical myocardium consistent with myocardial edema; note relative sparing of basal myocardium (white arrow). (C) Cardiac magnetic resonance imaging with delayed gadolinium sequence, 2-chamber view. The white arrow indicates the left ventricular apex with subendocardial enhancement. aVF, augmented vector foot; aVL, augmented vector left; aVR, augmented vector right; V1-V6, precordial leads; I-III, limb leads.
