Echocardiogram Ischemia STEMI

Here is the EMS ECG: Obviously massive diffuse subendocardial ischemia, with profound STD and STE in aVR Of course this pattern is most often seen from etoliogies other than ACS. The ECG only tells you there is ischemia, not the etiology of it. What do you think the echocardiogram shows? NTG drip started. Pain better still.

Important point: when there is diffuse subendocardial ischemia but no OMI, a wall motion abnormality will not necessarily be present. See this post: What do you think the echocardiogram shows in this case? They agreed ischemia was likely in the setting of demand given DKA and infection. 40 mg of furosemide was given.

He was rushed by residents into our critical care room with a diagnosis of STEMI, and they handed me this ECG: There is sinus tachycardia with ST elevation in II, III, and aVF, as well as V4-V6. At first glance, it seems the patient is having a STEMI. ACS and STEMI generally do not cause tachycardia unless there is cardiogenic shock.

This is a 45 yo male who had an inferior STEMI 6 months prior, was found to have severe LAD and left main disease, and was supposed to be set up for CABG a few weeks later, but did not follow up. But it could be anterior STEMI. 40% of anterior STEMI has upward concavity in all of leads V2-V6. is likely anterior STEMI).

This ECG was read as “No STEMI” with no prior available for comparison. It is true this ECG does not meet STEMI criteria (there is 1.0 The patient has also developed sinus bradycardia, which may result from right coronary artery ischemia to the SA node. Instead we discussed 5 minute delays for the STEMI(+) OMI patients.

A prehospital “STEMI” activation was called on a 75 year old male ( Patient 1 ) with a history of hyperlipidemia and LAD and Cx OMI with stent placement. Whether these EKGs show myocarditis, a normal variant, or something else, they are overall not typical of transmural ischemia of the anterior or high lateral walls.

There is profound LVH with anterolateral ST elevation and reciprocal ST depression in II, III, aVF, and ST depression in V5 and V6 that could all be secondary to LVH or could represent ischemia superimposed on the repolarization abnormalities of LVH: note that wherever there is ST depression, it is associated with a very high voltage R-wave.
