Subtle ST Segment Elevation (OMI Pattern)

Key Points ACS Dynamics: Occluded arteries in ACS can spontaneously reperfuse and reocclude, making ECG findings variable. Limitations of Computer Interpretation: Subtle STE is often missed by computerized ECG interpretation;…

de Winter T Waves (OMI Pattern)

Key Points STEMI Equivalent: The de Winter ECG pattern is an uncommon STEMI equivalent indicative of an unstable proximal occlusion of the LAD (left anterior descending coronary artery). This pattern…

South African Flag Sign (OMI Pattern)

Key Points Pattern Recognition: The South African Flag Sign is characterized by: ST-segment elevation (STE) in leads I, aVL, and V2. ST-segment depression in lead III. Subtle but visually distinctive…

Aslanger Pattern (OMI Pattern)

Key Points STEMI Diagnosis and Contiguous Leads: While current guidelines typically require ST elevation (STE) in at least two contiguous leads for the diagnosis of STEMI, this practice is not…

OMI Patterns in Left Bundle Branch Block

Key Points Diagnosis in LBBB: LBBB does not exclude the diagnosis of occlusion myocardial infarction (OMI). Acute MI can be identified despite the repolarization changes that LBBB causes, particularly with…

Early Reciprocal Changes (OMI Pattern)

Key Points ACS Dynamics: ACS is complex and dynamic, with occluded arteries potentially reperfusing and reoccluding at any time. ECG Pattern Recognition: Mastering ECG pattern recognition in ACS is crucial…

New RBBB and LAFB in ACS (OMI Pattern)

Key Points Pattern Recognition: New-onset Right Bundle Branch Block (RBBB) and Left Anterior Fascicular Block (LAFB) occurring together is a high-risk ECG finding. Often associated with proximal Left Anterior Descending…

Terminal QRS Distortion (OMI Pattern)

Key Points Early Repolarization (ER): A common ECG finding that can produce widespread ST-segment elevation, often mimicking STEMI or acute pericarditis. ST Segment Morphology: Convex and horizontal ST-segment morphology is…
