In the available view of the sinus rhythm, we see normal variant STE which probably meets STEMI criteria in V4 and V5. In other words, the inferior "ST elevation" is due to the abnormal rhythm, and does not signify OMI or STEMI in any way. This situation has been named "Emery phenomenon." YOU TOO CAN HAVE THE PM Cardio AI BOT!!

Learning Points: Ectopic atrial rhythm can produce atrial repolarization findings that can be confused for acute ischemia, STEMI, or OMI. To the left of these tracings is schematic illustration of the Emery Phenomenon ( adapted from the 2015 post by Dr. Bojana Uzelac on Armel Carmona’s ECG Rhythms website ).
