Ventricular fibrillation is defined as?

Explanation:
Ventricular fibrillation is a life-threatening arrhythmia where the ventricles beat in a rapid, disorganized way due to chaotic electrical activity, so the heart cannot pump blood and the pulse is lost. That description—rapid irregular contractions that throw the heartbeat and pulse out of rhythm—best matches this disorganized, non-pumping rhythm. The other ideas miss key points: a rapid but regular beat is tachycardia, not fibrillation; a heart murmur is a sound from turbulent blood flow, not a rhythm disturbance; and a temporary loss of consciousness from low blood pressure describes syncope, not the underlying arrhythmia.
