Subtle STEMI

The Bottom Line - August 19, 2016 - By David Slessor
Ref: Electrocardiographic Differentiation of Early Repolarization from Subtle ST-Segment Elevation Myocardial Infarction - Smith S; Annals of Emergency Medicine 2012; 60(1):45-56, doi:10.1016/j.annemergmed.2012.02.015
"Clinical Question
Are there specific ECG characteristics that can differentiate between anterior ST-elevation myocardial infarction (STEMI) and early repolarisation?
Authors’ Conclusions
R-wave amplitude is lower, ST-segment elevation greater, and QTc longer for subtle anterior STEMI versus early repolarisation. In combination with other clinical data, this derived and validated ECG equation could be an important adjunct in the diagnosis of anterior STEMI.

The Bottom Line
This study derived and validated an ECG score that can help differentiate anterior ST elevation from early repolorisation.
Current on-line apps and calculators are available to help calculate this score but need to be used in the right patient by a clinician who understands this score in the context of the whole patient presentation."
