Magnesium is of great importance in cardiac arrhythmias. It increases the ventricular threshold for fibrillation. Sinus node refractoriness and conduction in the AV node are both prolonged. Main indications for intravenous application of magnesium are Torsade de pointes tachycardias, digitalis toxicity induced tachyarrhythmias and multifocal atrial tachycardias. Additionally, patients with ventricular arrhythmias due to overdoses of neuroleptics or tricyclic antidepressants may profit from i.v… CONTINUE READING
