Which intervention is recommended as the initial management for unstable tachycardia with wide complex VT (monomorphic) according to the protocol?

• A. Synchronized Cardioversion
• B. Amiodarone
• C. Defibrillation
• D. Adenosine

Answer: (A)

When a patient has unstable tachycardia with a wide, monomorphic VT and is showing signs of poor perfusion, the priority is to restore hemodynamic stability as quickly as possible. Delivering a synchronized electrical shock targets the rhythm at the QRS complex, which interrupts the VT while preventing random, dangerous shocks that could occur if delivered unsynchronized. This rapid, coordinated cardioversion can restore a stable rhythm and perfusion much faster than medications alone in an unstable patient. Antiarrhythmics like amiodarone can be used if the patient remains unstable after cardioversion or as a subsequent measure, but they do not provide the immediate stabilization that synchronized cardioversion does. Adenosine is not appropriate for VT, as it targets certain SVTs with narrow QRS complexes and can be ineffective or harmful in VT. Defibrillation is reserved for pulseless VT or cardiac arrest, not for a patient with a pulse who is unstable.
