Bedside ED ultrasound showed exceedingly poor global LV function, and no B lines. I was there and said, "No, I think this is all due to severe chronic cardiomyopathy and cardiac arrest due to primary ventricular fibrillation, not due to ACS." _ Why did I say that? Pacemaker mediated tachycardia! What do you think?

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