Key Takeaways
de Winter T Waves: STEMI-Equivalent Anterior Occlusion Pattern Without Classic ST Elevation: integrate rate, rhythm, axis, intervals, and ischemia signs before labeling a single “diagnosis of the strip.”
Stability is defined by perfusion, work of breathing, mentation, and trends—not one reassuring blood pressure.
