What is the initial management step for ventricular fibrillation and pulseless ventricular tachycardia?

• A. Defibrillation
• B. Chest compressions only
• C. Intravenous amiodarone alone
• D. Observation and monitoring

Answer: (A)

Immediate defibrillation is the treatment of choice for ventricular fibrillation and pulseless ventricular tachycardia because these rhythms are chaotic, cannot produce a pulse, and are considered shockable. Delivering a high-energy shock aims to terminate the disorganized electrical activity so the heart can regain a perfusing rhythm. If possible, defibrillate as soon as the defibrillator is ready, then resume CPR and reassess. Chest compressions remain essential, especially if a shock is not immediately available or after a shock, but they do not correct the arrhythmia on their own. Antiarrhythmics like amiodarone are used after defibrillation attempts for persistent arrest, not as the initial maneuver. Observation and monitoring won’t treat a pulseless event.
