Taking a step back , remember that sinus tachycardia is less commonly seen in OMI (except in cases of impending cardiogenic shock). Answer : Bedside ultrasound! Smith : RV infarct may also have this appearance on ultrasound. So hypoxia without B lines on lung ultrasound strongly weights toward PE. Both were wrong.

Shocked x 2 without effect. Pads were placed with ultrasound guidance, so they were in the correct position. As I discussed and documented in Lesson 1 of My Comment at the bottom of the page in the April 2, 2022 post of Dr. Smith's ECG Blog — certain patients may remain in sustained VT not only for hours — but even for days!

The patient in today’s case presented in cardiogenic shock from proximal LAD occlusion, in conjunction with a subtotally stenosed LMCA. Another approach is sympathetic chain (stellate ganglion) blockade if you have the skills to do it: it requires some expertise and ultrasound guidance. RCA — 100% proximal occlussion.

Case continued A bedside ultrasound showed diminished LV EF and of course bradycardia. RVMI explains part of the shock. The April 17, 2022 post ( Leads V1,V2 misplacement ).

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. As for the ECG, it could represent OMI, but RBBB is also a clue that it may be PE. There is sinus tachycardia at ~100/minute.

Tachycardia is unusual for OMI, unless the patient is in cardiogenic shock (or getting close). A bedside ultrasound should be done to assess volume and other etiologies of tachycardia, but if no cause of type 2 MI is found, the cath lab should be activated NOW. The October 21, 2022 post — for " artifactual VT".
