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.

Normally, concavity in ST segments suggests absence of anterior ischemia (though concavity by itself is not reassuring - see this study ). In there ECG evidence of possible ongoing ischemia? (ie, IMPRESSION: I’d interpret this tracing as consistent with LVH and/or “strain” and/or ischemia. THANK YOU Dr. Lee!

This ECG is all but diagnostic of subepicardial ischemia of the anterior, lateral, and inferior walls, most likely due to Occlusion MI (OMI), probably of the LAD. Expert ECG interpretation could have prevented this man's cardiac arrest, and almost certainly would have resulted in a much smaller MI and therefore better long term prognosis.

See these other related cases: A patient with cardiac arrest, ROSC, and right bundle branch block (RBBB). Appreciation of this PEARL #8 is important for assessing ischemia because hyperkalemia may either mimic or mask ischemic ECG changes! Is this just right bundle branch block?

If a patient presents with chest pain and a normal heart rate, or with shockable cardiac arrest, then ischemic appearing ST elevation is STEMI until proven otherwise.

These include ( among others ) — acute febrile illness — variations in autonomic tone — hypothermia — ischemia-infarction — malignant arrhythmias — cardiac arrest — and especially Hyperkalemia. Patients with such conditions that may transiently mimic the ECG findings of a Brugada-1 pattern are said to have Brugada Phenocopy.
