STE limited to aVR is due to diffuse subendocardial ischemia, but what of STE in both aVR and V1? The additional ST Elevation in V1 is not usually seen with diffuse subendocardial ischemia, and suggests that something else, like STEMI from LAD occlusion, could be present. Was this: 1) ACS with ischemia and spontaneous reperfusion?

This ECG is diagnostic of diffuse subendocardial ischemia. What is the utility of a head CT in cardiac arrest? We found intracranial hemorrhage in 2% of non-traumatic cardiac arrest patients, and in 4 others the presence of cerebral edema changed management. We studied this and published the abstract below in 2010.

His response: “subendocardial ischemia. Smith : It should be noted that, in subendocardial ischemia, in contrast to OMI, absence of wall motion abnormality is common. With the history of Afib, CTA abdomen was ordered to r/o mesenteric ischemia vs ischemic colitis vs small bowel obstruction. Anything more on history?

Followup ECG: No Change Absence of evolution is the best evidence against ischemia as the etiology. I was taught that the tell-tale sign of ischemia vs an electrical abnormality was in the hx, i.e. chest pain for the ischemia and potential syncope for brugada. Ischemia/infarction. Acute febrile illness. Hypothermia.

mg reduced the risk of cardiovascular death, MI or heart attack, ischemic stroke, or ischemia-driven coronary revascularization by 31% compared with placebo.34 2013;368(21):2004-2013.

Steve, what do you think of this ECG in this Cardiac Arrest Patient?" A woman in her 50s with dyspnea and bradycardia A patient with cardiac arrest, ROSC, and right bundle branch block (RBBB). HyperKalemia with Cardiac Arrest. Is this just right bundle branch block?

This suggests ischemia of uncertain duration. Unfortunately, before this could be accomplished — the patient went into cardiac arrest. She was successfully resuscitated — with a post-arrest rhythm similar to that seen in Figure-1. Cardiac cath did not reveal significant coronary disease!
