The morphology of V2-V4 is very specific in my experience for acute right heart strain (which has many potential etiologies, but none more common and important in EM than acute pulmonary embolism). He had multiple cardiac arrests with ROSC regained each time. CT angiogram showed extensive saddle pulmonary embolism.

Bedside cardiac ultrasound showed moderately decreased LV function. CT of the chest showed no pulmonary embolism but bibasilar infiltrates. See this post: How a pause can cause cardiac arrest 2. She was intubated. The plan: 1. Place temporary pacemaker 3. Discontinue amiodarone, since it prolongs the QT 4.

A bedside cardiac ultrasound was normal, with no effusion. Clinically — despite an initial 2-fold increased troponin, the normal bedside Echo was reassuring against OMI or pulmonary embolism. He had the following EKG recorded: Low voltage, suggests effusion. see Ken's discussion of low voltage below) There is a QS-wave in V2.

A bedside cardiac ultrasound was recorded: Here is a still image of the echo: The red arrows outline the right ventricle and the yellow arrows outline the left ventricle chamber. It makes pulmonary embolism (PE) very likely. Second: what does the ultrasound tell us about the condition? He was in profound shock.

Smith comment: before reading anything else, this case screamed pulmonary embolism to me. I would do bedside ultrasound to look at the RV, look for B lines as a cause of hypoxia (which would support OMI, and argue against PE), and if any doubt persists, a rapid CT pulmonary angiogram.

I suspect this is Type 2 MI due to prolonged severe hypotension from cardiac arrest. The ways to tell for certain include intravascular ultrasound (to look for extra-luminal plaque with rupture) or "optical coherence tomography," something I am entirely unfamiliar with. pulmonary embolism, sepsis, etc.), myocarditis).
