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. Circulation 122:Abstract 101. Kurkciyan et al.

They shocked him twice before return of spontaneous circulation. This was interpreted by the treating clinicians as not showing any evidence of ischemia. When EMS arrived the patient was in ventricular fibrillation. He was intubated in the field and sedated upon arrival at the hospital.

If there is polymorphic VT with a long QT on the baseline ECG, then generally we call that Torsades, but Non-Torsades Polymorphic VT can result from ischemia alone. If cardiac arrest from hypokalemia is imminent (i.e., mEq of K pushed fast and circulated theoretically would raise serum K immediately by 1.0 mg/dL [1.03 0.16

There is no definite evidence of acute ischemia. (ie, Simply stated — t he patient was having recurrent PMVT without Q Tc prolongation, and without evidence of ongoing transmural ischemia. ( Some residual ischemia in the infarct border might still be present. Both episodes are initiated by an "R-on-T" phenomenon.
