Again, it is common to have an ECG that shows apparent subendocardial ischemia after resuscitation from cardiac arrest, after defibrillation, and after cardioversion. The estimated left ventricular ejection fraction is 58 % Aortic stenosis, mild, 9.0 We found that 38% of out of hospital ventricular fibrillation was due to STEMI.

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. TIMI-0 flow.

He was resuscitated with chest compressions and defibrillation and 1 mg of epinephrine. An echocardiogram confirmed aortic stenosis with a large pressure gradient. Thus, this patient had increased ST elevation (current of injury) superimposed on the ST elevation of LVH and simulating STEMI. His initial ECG is shown here.

She was found to be in ventricular fibrillation and was defibrillated 8 times without a single, even transient, conversion out of fibrillation. She was immediately intubated during continued compressions, then underwent a 9th defibrillation, which resulted in an organized rhythm at 42 minutes after initial arrest. see below).

She was defibrillated and resuscitated. 1-4 Surprisingly, serial angiographic studies have revealed that the plaque at the site of the culprit lesion of a future acute myocardial infarction often does not cause stenosis that, as seen on the antecedent angiogram, is sufficiently severe to limit flow. Learning Points: 1.

When the ICD was finally interrogated, the syncopal events and shocks correlated with two VF events that were defibrillated successfully. 90% stenosis of the proximal ramus intermedius, pre procedure TIMI II flow The ramus intermedius is a normal variant on coronary anatomy that arises between the LAD and LCX.
