What is the initial management for unstable ventricular tachycardia?

Unstable ventricular tachycardia requires rapid rhythm control with synchronized cardioversion to restore a perfusing rhythm. When a patient with VT is hemodynamically unstable, the priority is to convert the rhythm quickly while avoiding accidental shock during the vulnerable period, which synchronized cardioversion does by delivering the shock in rhythm with the QRS complex. This helps improve perfusion and reduces the risk of arrest. If the patient were pulseless, the approach shifts to defibrillation (unsynchronized), since there is no cardiac output to preserve. Magnesium sulfate is reserved for torsades de pointes or magnesium deficiency, not routine unstable VT. Adenosine is not effective for ventricular tachycardia and is used for certain supraventricular tachycardias instead.
