Magnesium sulfate is an anti arrhythmic agents. Magnesium sulfate is useful in treating patient with torsade de pointes, digoxin toxicity which lead to ventricular dsyarrhythmia and after by pass surgery with hope in preventing patient developing ventricular arrhythmias or supra ventricular tachycardia.
Magnesium sulfate will be given intravenously. Magnesium sulfate will affect the permeability of the membrane for ion transport. This will cause the slowness of the AV node conduction and reduction in cardiac excitability after cardiac surgery mostly due to hypomagnesemia. Magnesium sulfate is also useful as an osmotic purgative.
Magnesium sulfate commonly associated with side effects such as weakness of the muscle.
