He was defibrillated into VT. He then underwent dual sequential defibrillation into asystole. See these related cases: Cardiac arrest, defibrillated, diffuse ST depression and ST Elevation in aVR. Cardiac arrest #3: ST depression, Is it STEMI? This patient was witnessed by bystanders to collapse. They started CPR.

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. VF was refractory to amiodarone, lidocaine, double-sequential defibrillation, esmolol, etc. Sensitivity was 87% for OMI in our validation study (it was 34% for STEMI criteria).

She was unable to be defibrillated but was cannulated and placed on ECMO in our Emergency Department (ECLS - extracorporeal life support). After good ECMO flow was established, she was successfully defibrillated. Here is a case of ECMO defibrillation with near shark fin that was due to proximal LAD occlusion. The K was normal.

This certainly looks like an anterior STEMI (proximal LAD occlusion), with STE and hyperacute T-waves (HATW) in V2-V6 and I and aVL. How do you explain the anterior STEMI(+)OMI immediately after ROSC evolving into posterior OMI 30 minutes later? This caused a type 2 anterior STEMI. The April 8, 2022 post by Drs.

The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. He required multiple defibrillations within a period of a few hours. There is no definite evidence of acute ischemia. (ie, This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation.

There’s inferior ST depression which is reciprocal to subtle lateral convex ST elevation, and the precordial T waves are subtly hyperacute – all concerning for STEMI(-)OMI of proximal LAD. There’s ST elevation I/aVL/V2 that meet STEMI criteria. This is obvious STEMI(+)OMI of proximal LAD. Non-STEMI or STEMI(-)OMI?

Are Some Cardiologists Really Limited by Strict Adherence to STEMI millimeter criteria? He was found in ventricular fibrillation and defibrillated, then brought to a local ED which does not have a cath lab. This is the response he got: Interventionist: "No STEMI, no cath. It is a STEMI equivalent.
