Explanation:
Detailed explanation-1: -Ventricular fibrillation is a potentially fatal, uncoordinated series of very rapid, ineffective contractions of the ventricles (lower chambers of the heart) caused by many chaotic electrical impulses. Ventricular fibrillation causes unconsciousness in seconds, and if the disorder is not rapidly treated, death follows.
Detailed explanation-2: -In atrial fibrillation, the atria beat irregularly. In atrial flutter, the atria beat regularly, but faster than usual and more often than the ventricles, so you may have four atrial beats to every one ventricular beat.
