Key Takeaways
RV Strain and Pulmonary Embolism: S1Q3T3 Teaching, T Inversions V1–V4, and Bedside Correlation Limits: 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.
Serial ECG acquisition is part of safe care when symptoms evolve, electrolytes shift, or reperfusion therapy is considered.
Escalation language should match institutional pathways; educational articles do not replace medical direction.
