Magnesium para Cardiac Arrhythmia

B Evidencia Al menos un ensayo aleatorizado lo respalda, con resultados mayoritariamente consistentes.

IV magnesium is well-established for torsades de pointes. Oral supplementation may reduce PVCs and atrial ectopy in hypomagnesemic patients. Acts as a natural calcium channel blocker stabilizing cardiac electrical activity.
