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…

Precordial Swirl (OMI Pattern)

Key Points Definition: The precordial swirl sign refers to a rotational pattern of ST-segment abnormalities across the precordial leads, suggesting a dynamic and evolving occlusion myocardial infarction (OMI). It is…

ST Depression V1-V4 (Posterior OMI Pattern)

Key Points Most Missed STEMI: Isolated posterior MI is the most commonly missed occlusion MI due to the absence of ST elevation on standard 12-lead ECG. ECG Pattern of Posterior…

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;…

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…

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…
