Supports IV magnesium for torsades; leaves open prospective trials on prophylactic targets in other tachyarrhythmias.
Maintaining serum magnesium levels above 2 mEq/L is crucial for stabilizing cardiac electrical activity and preventing both supraventricular and ventricular tachyarrhythmias.
E et al. (2023) conducted a review in Cardiac arrhythmias and magnesium imbalance. Intravenous magnesium sulfate was evaluated. Extracellular magnesium is critical for cardiac electrical stability, with hypomagnesemia promoting tachyarrhythmias and intravenous magnesium sulfate acting as the treatment of choice for torsades de pointes.
