Maternal ventricular tachycardia associated with hypomagnesemia.
We present a rare case of recurrent sustained maternal ventricular tachycardia associated with hypomagnesemia. The frequency of this arrhythmia was markedly reduced with magnesium sulfate therapy. Both maternal and fetal outcomes were good. To the best of our knowledge this is the first description of maternal ventricular tachycardia that was associated with hypomagnesemia and did not require treatment with conventional antiarrhythmic medications. We discuss the possible underlying pathophysiologic causes of this condition.
