Background
- Its presence must be explained (there is no "nonspecific ST elevation")
- Not a specific marker for STEMI
DDX
- Myocardial Ischemia
- ATEMI
- Wellens' Syndrome
- Ventricular aneurysm
- Coronary spasm
- Pericarditis
- Early repolarization
- LBBB
- LVH
- Misc
- Meds: TCA, digoxin
- Pacing
- RV pacing = LBBB
- Hyperkalemia
- Hypothermia
- "Osborn J waves"
- Brugada Syndrome
Early Repolarization versus STEMI
- Early Repolarization
- ST elevation <4mm
- Notched J point
- Concave or saddle-back ST morphology
- no reciprocal changes
LVH versus STEMI
- Difficult to exclude MI in pt with LVH (pt already at risk for MI)
- Best aid is prior ECG or serial ECGs
LBBB versus STEMI
