What is ventricular fibrillation?
Ventricular fibrillation is a type of abnormal heart rhythm (arrhythmia). As a result, the heart doesn&'t pump blood to the rest of the body.
Ventricular fibrillation is an emergency that requires immediate medical attention. It's the most frequent cause of sudden cardiac death.
Symptoms
Collapse and loss of consciousness is the most common symptom of ventricular fibrillation.
