[Magnesium salts in the treatment of ventricular tachycardia].
We report the results of magnesium sulphate (MgSO4) infusion in 10 patients with different ventricular arrhythmias: 6 torsade de pointes (2 with total A-V block, 1 with acute myocardial infarction and 3 with lengthening of the Q-Tc due to antiarrhythmic and/or diuretic treatment), 1 bidirectional ventricular tachycardia (on chronic treatment with digoxin (0.5 mg/day) and diuretics), and 3 polymorphic ventricular ectopic beats plus ventricular tachycardia runs (2 with hypertensive and 1 with ischemic cardiomyopathy). MgSO4 in normal saline was given at low rate (50 mg/min) and continued 2 hours after disappearance of arrhythmia, and the infusion was repeated at the same rate for 60-90 min twice daily for the next 3-4 days. In all patients the drug was effective and no side effects were observed. The heart rate and Q-Tc interval remained unchanged from baseline values. Serum creatinine concentration was normal. Serum Mg++, 60 minutes after the beginning of the infusion, was comparable to control values in all the patients, except 2 with hypomagnesemia. Finally, we can conclude that MgSO4 is an useful therapeutic tool for the treatment of various ventricular tachycardias.
