Final answer:
Ventricular fibrillation is a ventricular arrhythmia that requires immediate intervention. Defibrillation is the most common treatment for ventricular fibrillation.
Step-by-step explanation:
Ventricular fibrillation is a ventricular arrhythmia that requires immediate intervention. In this condition, the ventricles of the heart are not contracting but quivering, and there are no discernable waves noted throughout the tracing. Ventricular fibrillation is a medical emergency that can lead to brain death if untreated for even a few minutes. The most common treatment for ventricular fibrillation is defibrillation, which applies an electrical charge to the heart to establish a normal sinus rhythm.
