Inferior ST-elevation myocardial infarction
coreA 61-year-old with one hour of crushing chest pressure and nausea.

Calipers:2000 ms50.0 small boxes30 bpm if R-RDrag the orange markers. One small box = 40 ms.
Recorded tracingA real 12-lead of this rhythm. The strip above is a drawn model; this is the paper.
Key findings
- STE in II, III, aVF
- Reciprocal depression in aVL
- Bradycardia and AV block are companions
Learning points
- Reciprocal depression is the confirmation that elevation is real: pericarditis has no reciprocal changes except in aVR/V1.
- Right-sided leads (V4R) belong on every inferior STEMI: RV infarction changes fluid and nitrate decisions.
