Magnesium is often implemented in the management of torsades de pointes.Although its mechanism has not been fully elucidated,magnesium may exert its pharmacologic effect by prolonging conduction time;however,its role has not been clearly delineated.Intravenous magnesium may be effective whether or not a patient is eumagnesemic (having a normal serum magnesium level).
