Conclusion

Our study results suggest that prophylactic administration of intravenous magnesium sulfate prevents increases in the QT and QTc interval 30 minutes after the last infusion of ibutilide in patients with atrial fibrillation or flutter. No other changes in standard electrocardiographic variables, QT or QTc interval dispersion, or heart rate were observed.
