A STEMI is generally defined as an Electrocardiogram (EKG) with ST elevation of greater than 1 mm in 2 or more contiguous leads. It has also been defined as a "new" Left Bundle Branch Block (LBBB ...

Recall that a right bundle branch block does not stop us from detecting a STEMI on an ECG. Below are some examples to review in order to recognize anterior and inferior STEMIs with a RBBB.

One study examined the prognostic significance of various electrocardiographic (ECG) patterns in patients with ST elevation myocardial infarction (STEMI) and found that LBBB was associated with a ...

These recent studies by Jain and Kontos demonstrate that most patients with chest pain and a "new" LBBB do not have a STEMI, and call for consideration of other factors in determining the ...
