Question

Quizplus · Accepted Answer

Ventricular fibrillation is a life-threatening heart rhythm that results in rapid, erratic electrical impulses. These impulses cause the ventricles to quiver uselessly instead of pumping blood, leading to an inadequate blood supply to the body's organs. It is not an absence of contractions, a type of heart block, or an apparatus; those describe other conditions or treatments.
