For example, is a patient with a 3-variable result of 30 dramatically more likely to have subtle LAD occlusion than another patient with a result of 25? Or is it simply a binary cutoff.

That said, as stated in the 2nd sentence of this post (above) — There is NOTHING subtle about this tracing. Anyone who misreads this ECG in a patient with chest pain as reflecting “early repolarization” should (in my opinion) simply not be reading ECGs on the “front line”, but instead NEEDS to study/practice more on their ECG interpretation skills. Otherwise, I just don’t understand criteria that describe the amount of ST elevation in this case as “not enough for a stemi … “. QRS amplitude in V2 and V3 is tiny (which of itself is highly suggestive in association with the T waves in these leads as an acute ongoing stemi) — and the relative amount of ST elevation in V3 is about 2/3 the height of the R wave in this lead. Bottom Line: The fact that emergency providers continue to misread tracings like these is evidence of the IMPORTANCE of your ECG Blog as playing an essential role in improving emergency ECG interpretation.
