Last night, I had a patient present with acute dyspnea, tachy in the 150s. She had a h/o prior PE 5 years ago that she completed anticoagulation for. EKG shown below has some TWI in anteroinferior leads (c/w RHS), and a nice Q wave in III (not really an S1, but impressive Q3T3).
Patient was started on a heparin ggt even prior to CT (slice shown below). Bedside echo also revealed enlarged RV. She had b/l PEs. She was hemodynamically stable, so this was considered a submassive PE.
