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.

With respect to timing, for cardiac arrest with a shockable rhythm, it may be reasonable to administer epinephrine after initial defibrillation attempts have failed. Consider administering epinephrine after defibrillation in those with shockable rhythms. Editorial Comment : Yes to PCI after arrest with STEMI on ECG.

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).

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.

It doesn’t meet any conventional STEMI criteria, but there is patently obvious increased area under the curve. Despite immediate chest compressions, and multiple rounds of defibrillation, he could not be resuscitated. No appreciable skin pallor. He reported to be a social drinker, but used tobacco products daily. Is this OMI?

He underwent further standard resuscitation EXCEPT that we applied the Inspiratory Threshold Device ( ResQPod ) AND applied Dual Sequential Defibrillation (this simply means we applied 2 sets of pads, had 2 defib machines, and defibrillated with both with only a fraction of one second separating each defibrillation.

Defibrillation is the treatment of choice in these cases but does not often result in sustained ROSC ( Kudenchuk et al 2006). There is evidence that taking those patients with ROSC and EKG showing STEMI directly for angiography +/- angioplasty is associated with positive patient-oriented outcomes.

The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. He required multiple defibrillations within a period of a few hours. This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation. The below ECG was recorded. What do you think?

If it is STEMI, it would have to be RBBB with STEMI. The patient presented with chest pain. Here is the ECG: What do you think? I frankly did not know what to think. Is it Brugada pattern? But in a very unusual pattern. This physician thought it was an anterior MI and gave thrombolytics. All troponins were negative. Only 1-5% have OMI.

So there is definitely no STEMI, and the STE is normal. But after reading this blog, you all know that most OMI do NOT meet STEMI criteria. Bedside echo revealed anteroseptal wall motion abnormality at which point I activated a code STEMI. Defibrillated out of v fib in the cath lab. But it simply says "normal."

She was defibrillated and resuscitated. V1 has 0.5 mm of ST segment elevation, V2 and V3 have 1 mm of elevation, v4 has 2 mm of elevation and v5 around 1.5 mm of elevation. More notably there are hyperacute T waves in V3 through V5. There is also T wave inversion In aVL with a very small amount of ST segment depression. Learning Points: 1.

He was resuscitated with chest compressions and defibrillation and 1 mg of epinephrine. Thus, this patient had increased ST elevation (current of injury) superimposed on the ST elevation of LVH and simulating STEMI. This young male had ventricular fibrillation during a triathlon. His initial ECG is shown here. He awoke and did well.

RBBB in acute STEMI has a very high mortality. But here there is a large degree of ST elevation in V2-V6, I, and aVL. The paramedics activated the cath lab from the field. Were it not for this prehospital ECG and the cardiac arrest, the diagnosis may have been significantly delayed.

It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation. He reportedly told his family "I think I'm having a heart attack", then they immediately drove him to the ED, and he was able to ambulate into the triage area before he collapsed and became unresponsive. CPR was initiated immediately.
