11-Rapid ECG Differential Diagnoses – High-Yield Clinical Patterns

Built for acute care and emergency medicine rotations, this video outlines rapid ECG differential diagnoses for common high-yield clinical presentations. We cover atrial fibrillation with slow ventricular response (toxicological vs. nodal causes), provide a clean tachydysrhythmia matrix (narrow vs. wide, regular vs. irregular), and walk through differentials for axis deviation, low voltage, wide QRS vs. long QT, prominent R waves in lead V1 ), peaked T waves, and localized vs. diffuse ST-segment elevation.
