Which abbreviation is used to describe the heart rhythm abnormality that can lead to sudden cardiac death?

Explanation:
This item tests recognizing the rhythm that can cause sudden cardiac death. The abbreviation for the dangerous heart rhythm is VF, which stands for ventricular fibrillation. In ven​tric​u​lar fibrillation, the ventricles quiver chaotically rather than pump effectively, so no meaningful blood flow is created. That rapid loss of perfusion leads to sudden collapse unless defibrillation and CPR are provided immediately. The other options aren’t rhythm terms: an AED is a device used to deliver a shock, WBC refers to white blood cells, and CXR is a chest X-ray.
