Atrial flutter with 2:1 conduction. The atrial flutter rate is approximately 200 bpm, with 2:1 AV conduction resulting in ventricular rate almost exactly 100 bpm. Further history revealed she had new onset atrial flutter soon after her aortic surgery, and was put on flecainide approximately 1 month ago.

If this STD were due to LVH or to subendocardial ischemia, rather than posterior OMI, it would be maximal in V5 and V6. To me, this looks like pulmonary edema. B-line predominance bilateral lungs indicates pulmonary edema. B-line predominance bilateral lungs indicates pulmonary edema. Here are a few clips.

Re-entrant tachycardias (atrial flutter, PSVT, AVRT, VT) have constant regular heart rates, whereas sinus tachycardia will usually gradually change rate with differing conditions (for instance, after infusion of fluid and BP increase, sinus tach rate might decrease from 130 to 125, for instance). So there is a re-entrant rhythm.

The bedside echo showed a large RV (Does this mean there is a pulmonary embolism as the etiology?) The rhythm is 2:1 atrial flutter. The flutter waves can conceal or mimic ischemic repolarization findings, but here I don't see any obvious findings of OMI or subendocardial ischemia. Lots of info here.

Evidence of acute ischemia (may be subtle) vii. Of the 67 patients who underwent targeted tests, suspected diagnoses were confirmed in 49 (73%) patients: aortic stenosis (n = 8, 1%), pulmonary embolism (n = 8, 1%), seizures/stroke (n = 30, 5%), and other diseases (n = 3). Left BBB vi. Pathologic Q-waves viii. LVH or RV d.
