In addressing unstable arrhythmias during Advanced Cardiovascular Life Support (ACLS), synchronized cardioversion is the preferred method because it effectively delivers a controlled electrical shock during a specific part of the cardiac cycle, thereby minimizing the risk of inducing ventricular fibrillation.

Unstable arrhythmias, such as rapid atrial fibrillation or ventricular tachycardia with a pulse, can lead to hemodynamic instability, and synchronized cardioversion can quickly restore a normal rhythm and improve cardiac output. It is particularly valuable for patients who are symptomatic and at risk of serious complications.

While cardiac pacing is useful for certain bradyarrhythmias, defibrillation is primarily used for pulseless ventricular tachycardia or ventricular fibrillation and is not suitable for tachyarrhythmias that still have a perfusing pulse. Relying solely on medications may not provide an immediate or effective resolution to unstable situations where rapid intervention is critical. Synchronized cardioversion provides a balance of urgency and safety, making it the optimal choice in these settings.
