Angioplasty STEMI Tachycardia

Precordial ST depression may be subendocardial ischemia or posterior STEMI. If you thought it might be a posterior STEMI, then you might have ordered a posterior ECG [change leads V4-V6 around to the back (V7-V9)]. Notice there is tachycardia. So there was 3-vessel disease, but with an acute posterior STEMI.

This point is particularly relevant regarding ECG #2 — because sinus tachycardia is seen on this earlier ECG. This blog post reviews the basics for predicting the " C ulprit" A rtery — as well as the importance of the term, " O MI" ( = O cclusion-based MI ) as an improvement from the outdated STEMI paradigm.

There is sinus tachycardia (do not be fooled into thinking this is VT or another wide complex tachycardia!) Code STEMI was activated. A man in his 80s with chest pain What, besides large anterior STEMI, is so ominous about this ECG? She was alert and oriented and hypotensive with initial BP 70/50.

When total LM occlusion does present with STE in aVR, there is ALWAYS ST Elevation elsewhere which makes STEMI obvious; in other words, STE is never limited to only aVR but instead it is part of a massive and usually obvious STEMI. All are, however, clearly massive STEMI. This is her ECG: An obvious STEMI, but which artery?

The Queen of Hearts correctly says: Smith : Why is this ECG which manifests so much ST Elevation NOT a STEMI (even if it were a 60 year old with chest pain)? In addition to sinus tachycardia, the only abnormalities listed by the computer were "low voltage, precordial leads" and "anteroseptal infarct, old.Q Physician: "No STEMI."

Later, she developed chest pain again, and had this ECG recorded: Obvious Anterior OMI that is also a STEMI Coronary angiogram- --Right dominant coronary artery system --The left main artery was normal in appearance and free of obstructive disease. --The Thus, Wellens' syndrome should be thought of as a transient OMI or transient STEMI.
