Key Takeaways
- CAT-Style Adaptive ECG Practice: Building Momentum for RN Learners With Weak-Area Targeting and Confidence Loops: 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.
