What should be administered for suspected Torsades de Pointes?

Explanation:
Magnesium is the treatment of choice for torsades de pointes because it helps stabilize the cardiac membrane and suppresses the early afterdepolarizations that drive this rhythm, reducing the likelihood of recurrence even when magnesium levels are normal. The recommended dose is 2 g given IV or IO, and it can be repeated if the arrhythmia persists. Defibrillation is reserved for pulseless or unstable presentations; lidocaine isn’t effective for torsades de pointes, and sodium bicarbonate isn’t indicated for this arrhythmia.
