How is torsades de pointes managed if the patient is unstable?

• A. Synchronized cardioversion
• B. Defibrillate (unsynchronized) + CPR
• C. Amiodarone infusion
• D. Vagal maneuvers

Answer: (A)

Torsades de pointes is a dangerous, rapidly pulsing ventricular tachyarrhythmia that can quickly compromise blood pressure and perfusion. When the patient is unstable, the priority is to restore a stable rhythm as quickly as possible. Synchronized cardioversion delivers a shock timed to the ECG waveform so the impulse terminates the tachycardia without provoking ventricular fibrillation, effectively reestablishing a perfusing rhythm. This immediate electrical intervention is essential in an unstable patient. If there were no pulse, the approach would shift to defibrillation (unsynchronized) with CPR, since there’s no effective circulation to support. Vagal maneuvers won’t correct this malignant rhythm, and amiodarone isn’t the first-line choice in torsades when the patient is unstable. Magnesium sulfate is an important adjunct treatment for torsades, but the urgent step to stabilize an unstable patient is synchronized cardioversion.
