What condition results from ventricular fibrillation?

Ventricular fibrillation is a serious condition in which the heart's electrical activity becomes disordered, leading to ineffective contractions of the ventricles. As a result, the heart cannot pump blood effectively, which causes a significant drop in blood circulation. This failure of the heart to maintain adequate blood flow can lead to cardiac arrest, a life-threatening situation where the heart stops beating altogether. During cardiac arrest, essential organs do not receive the oxygenated blood they need to function, making this condition critical and requiring immediate medical intervention, typically in the form of CPR or defibrillation.

The other options do not accurately represent the outcome of ventricular fibrillation. Slow blood circulation reflects an inadequate blood flow, but it doesn't capture the immediate and severe consequence of cardiac arrest. An increased heart rate is not a result of ventricular fibrillation; rather, it is often a symptom of other heart conditions. Healthy blood flow is the opposite of what occurs in ventricular fibrillation, as the condition disrupts normal circulation entirely.
