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.
