Posterior MI
- 4-10% of STEMIs are isolated posterior STEMI
- Most common type of missed MI…often misdiagnosed as NSTEMI
- The triad of ST depressions, upright Ts, and tall R waves (basically the equivalent of Q-waves) in V1-3 is suggestive of a Posterior MI
- Only 30% are revascularized in 90 minutes
- Usually associated with inferior or lateral MI due to RCA or circumflex occlusion
