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;…
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…
Key Points Isolated posterior occlusion MI is the most commonly missed “STEMI.” ST elevation is typically not seen on the standard 12-lead ECG in isolated posterior STEMI. Instead, it manifests…
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…
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…
Key Points Definition: The precordial swirl sign refers to a rotational pattern of ST-segment elevation across the precordial leads, suggesting a dynamic and evolving occlusion myocardial infarction (OMI). Mechanism: This…
