Anterior STEMI versus normal variant ST elevation

Here is a formula and on line calculator from Dr. Smith's ECG blog. The page also has a link to the primary source of the original research behind the formula. The QT interval factors in, as STEMI tends to lengthen the QT interval. It is important to note that the formula is intended for use in subtle cases (reflecting the population studied in the original research) and should not be applied in cases where STEMI is obvious. Moreover the formula is not reliable if there is electrocardiographic LVH.
