==Evaluation==
*Contour: Most→Least concerning for ischemia: Planar/Flat (90%) → Concave up (33%) → Downsloping with Asymmetric inverted T-wave (not ischemic/strain pattern) 
*Assume posterior STEMI or reciprocal changes to STEMI until proven otherwise 
*Indicators of ischemia: 
**>0.5mm depression from baseline (especially >1mm) in two or more contiguous leads 
**Transient depression 
**Morphology that is flat or downsloping 
*Strain:&nbsp;<br> 
**tall R wave 
**only in lateral leads (not anterior) 
**"checkbox" or asymmetric TWI
**down sloping pattern

==Differential Diagnosis==
*[[Posterior MI]] (including posterior [[STEMI]])
*RV strain
*[[NSTEMI]]
*Reciprocal changes
*[[Electrolyte Disorders]] (e.g. [[hypokalemia]])
*[[SVT]]
*[[RBBB]]/[[LBBB]]
*[[LVH]] with strain pattern (repolarization abnormality)
*[[Digoxin]] effect (not indicative of toxicity)
*[[Ventricular paced]] pattern
