Explanation:

Detailed explanation-1: -Ventricular fibrillation is a type of irregular heart rhythm (arrhythmia). During ventricular fibrillation, the lower heart chambers contract in a very rapid and uncoordinated manner.

Detailed explanation-2: -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-3: -An arrhythmia (also called dysrhythmia) is an abnormal heartbeat. Arrhythmias can start in different parts of your heart and they can be too fast, too slow or just irregular. Normally, your heart beats in an organized, coordinated way.
