But cardiac arrest is a period of near zero flow in the coronary arteries and causes SEVERE ischemia. Cardiac arrest #3: ST depression, Is it STEMI? Smith's ECG Blog ( See My Comment in the March 1, 2023 post) — DSI does not indicate acute coronary occlusion! It also does not uniformly indicate severe coronary disease.

Calcium is associated with harm but is still necessary in certain situations (hyperkalemia, calcium channel blocker overdose) (Level 3 recommendation: no benefit). Independent of a patient’s neurologic status, coronary angiography is reasonable in all post–cardiac arrest patients for whom coronary angiography is otherwise indicated.

The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. It shows a proximal LAD occlusion, in conjunction with a subtotally occluded LMCA ( Left Main Coronary Artery ). These are also the most commonly reported findings in toxic overdoses with ventricular arrhythmias being reported as the leading cause of death.

The 50-something patient with history of coronary stenting and slightly reduced LV ejection fraction. which would suggest reduced rates of major adverse cardiac events with coronary artery bypass grafting." On the other hand, stable EKG over an hour in the setting of ongoing acute coronary syndrome is again unusual.

A New Seizure in a Healthy 20-something More cases of long QT not measured correctly by computer (these are all fascinating ECGs/cases): Bupropion Overdose Followed by Cardiac Arrest and, Later, ST Elevation. Is it STEMI? Instead — it commonly reflects ischemia from severe underlying coronary disease. What is going on here?

Upwardly Concave ST Segment Morphology Is Common in Acute Left Anterior Descending Coronary Artery Occlusion. See this case: Pericarditis, or Anterior STEMI? 2 comments : 1. 40-50% of acute LAD occlusion have upwardly concave ST segments in all of V2-V5.

Written by Pendell Meyers A woman in her 70s with known prior coronary artery disease experienced acute chest pain and shortness of breath. Her history and ECG were interpreted as very concerning for acute coronary syndrome which might benefit from acute reperfusion therapy. Vital signs were within normal limits. hours since onset.
