Key Takeaways
- Epsilon Waves and ARVC Teaching: Low-Amplitude Potentials, Epsilon in V1, and VT Storm Context: 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.

Common mistakes
- Calling artifact “fine” without a repeat strip
- Ignoring clinical context when STEMI mimics are common
- Overconfidence from a single ECG snapshot
Step-by-step framework
- Confirm patient identity and clinical indication
- Rate → rhythm → axis → intervals → ischemia
- Compare to priors; document escalation triggers
