Diffuse ST elevation, without reciprocal ST depression, mostly in inferior limb leads and lateral precordial leads. This is very typical for pericarditis.

ACLS Revision: Subtle ECG findings in ACS

ST-segment elevation in lead aVR portends a worse prognosis in ACS and often predicts the need for CABG. Hyperacute T-waves are not necessarily tall, and small T-waves can still be hyperacute when paired with a low-amplitude QRS complex. The tall T-waves associated with hyperkalemia are sharp, pointy, symmetric, and have a narrow base. When in […]

Criteria for diagnosis of posterior STEMI include: ST-depression ≥0.5mm in leads V1-V3. Associated T-waves are either upright or inverted. Appearance of tall R-waves in V1-V2 (may be delayed). Recommended: posterior chest wall leads (V7-V9 ≥0.5 mm* ST-elevation). *may be decreased secondary to increased distance of posterior leads from heart.
