I took the patient to the criticalcare area and questioned him more on the way. Another ECG was recorded while awaiting the cath team: Now there is STEMI Let's look at that first (prehospital ECG) again: Very subtle! It was opened and stented. We activated the cath lab.
I immediately activated the criticalcare team and walked the patient to the criticalcare area, our "Stabilization Room." Opened and stented. This is why it is essential that the OMI/NOMI paradigm replace the STEMI/NonSTEMI paradigm. There are relatively large T-waves in V4-V6. Let's record another one."
Submitted and written by Alex Bracey, with edits by Pendell Meyers and Steve Smith: I was walking through the criticalcare section of the ED when I overheard a discussion about the following ECG. The patient was then taken to the cath lab an found to have a proximal RCA 100% thrombotic occlusion which was successfully stented.
The 50-something patient with history of coronary stenting and slightly reduced LV ejection fraction. This EKG was recorded as part of a standing order for criticalcare. In the setting of prior stenting and reduced left ventricular ejection fraction, would pursue a heart team revascularization approach Syntax score 28.5,
Here is his ED ECG: There is obvious infero-posterior STEMI. What are you worried about in addition to his STEMI? This was stented. Comments: STEMI with hypokalemia, especially with a long QT, puts the patient at very high risk of Torsades or Ventricular fibrillation (see many references, with abstracts, below).
He reports that this chest pain feels different than prior chest pain when he had his STEMI/OMI, but is unable to further describe chest pain. Sensitivity was 87% for OMI in our validation study (it was 34% for STEMI criteria). He has a h/o of 3 vessel disease and stents and his pain has been on and off for days.
There is an obvious inferior STEMI, but what else? Besides the obvious inferior STEMI, there is across the precordial leads also, especially in V1. This STE is diagnostic of Right Ventricular STEMI (RV MI). In fact, the STE is widespread, mimicking an anterior STEMI. He was successfully stented.
The PMCardio Queen of Hearts app asks you, before giving an interpretation of OMI ("STEMI-Equivalent"), whether the patient's clinical presentation is high risk for OMI. 20 cases with pseudonormalization Case continued The patient was moved to the criticalcare area, and cardiology was consulted.
It is diagnostic of OMI, but this is SUBACUTE OMI I sent this ECG to my "EKG Nerdz" friends, without any clinical info at all and they answered "OMI" The Queen said: "STEMI-Equivalent with High Confidence:" Notice she sees findings in both normal beats and PVCs. It was opened and stented. There is STE in V5-6.
After stent deployment, we often see improvement in the ST-T within seconds or minutes. Here is the final angiogram following placement of a stent in the ostial RCA. 2:04 PM, post stent deployment You can see that even after complete restoration of flow, the ECG still looks terrible, V most of all. link] Jentzer, J.
