Instructors Collection ECG: Inferior Wall, Posterior Wall, and Right Ventricular M.I.

The patient:    79-year-old man complaining of severe “burning” chest pain, radiating to his neck. Walking exacerbates his discomfort.  He has had nausea and vomiting for 24 hours. Past medical Hx includes high cholesterol and atrial fibrillation. Medications not known.

 

The ECGs:  These ECGs could be called “classic”.  There is a 100% occlusion of the right coronary artery (RCA), which was successfully repaired in the cath lab.  About 80% of inferior wall M.I.s are due to occlusion of the right coronary artery.  Depending on how proximal the occlusion is, we can expect a pattern on the ECG representing injury to all areas supplied by the RCA.  This “package deal” can include:

·         Inferior wall ST elevation.

·         Posterior wall extension.
