Chest pain: Are these really "Nonspecific ST-T wave abnormalities", as the cardiologist interpretation states?

Dr. Smith's ECG Blog

ST depression in lead AVL differentiates inferior ST-elevation myocardial infarction from pericarditis. Ischemic ST-segment depression maximal in V1-4 (versus V5-6) of any amplitude is specific for occlusion myocardial infarction (versus nonocclusive ischemia). Am J Emerg Med 2016 5. Meyers et al.

Two patients with chest pain, with QRS obscured: which was STEMI positive, and which had Occlusion MI?

Dr. Smith's ECG Blog

The initial computer and final cardiology interpretation was a differential: “ST elevation, consider early repolarization, pericarditis, or injury.” Emergency department Code STEMI patients with initial electrocardiogram labeled ‘normal’ by computer interpretation: a 7-year retrospective review.
