Key Takeaways
ECG Artifact: Muscle Tremor, Poor Contact, and VF Misidentification Risks in Monitored Environments: 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.
