[Therapeutic effectiveness of intravenous magnesium sulfate in tachyarrhythmia. Apropos of 4 clinical cases].
This is a report about four patients with tachyarrhythmias successfully treated with intravenous magnesium sulfate. In two cases (supraventricular tachycardia and torsade de pointes) because they were resistant to other antiarrhythmic drugs, and in the remaining two cases (paroxistic atrial fibrillation) because they presented characteristic features of magnesium depletion. The efficacy, the rapid onset of action and the absence of adverse reactions must be emphasized and the authors suggest that larger and randomized trials should be carried out, in order to establish the real place of magnesium sulfate in the antiarrhythmic armamentarium.
