ACLS Revision: Posterior STEMI

Posterior STEMI is 10 – 15% of all STEMIs, but it is often missed and here is why….

In the setting of ACS, ST depression in leads V1 – V3 means one of two things:
1. Anterior Ischemia
2. Posterior STEMI

Obviously these two entities are treated differently. So don’t be burned by ST depression in leads V1 – V3 and miss that posterior STEMI. Be sure to get posterior leads to confirm or exclude your diagnosis.
