[Sudden ventricular tachyarrhythmia immediately following hepatectomy in a patient with hypomagnesemia].
A 57-year-old male without pre- or intraoperative arrhythmia developed ventricular tachyarrhythmia immediately following hepatectomy. Postoperative examination of plasma electrolytes revealed severe hypomagnesemia (0.16 mmol.l-1). The arrhythmia may have been caused by hypomagnesemia and an imbalance between supply and demand of oxygen in the myocardium, due to hypovolemia and severe anemia from massive hemorrhage. We recommend that measurement of plasma magnesium concentration be included in all perioperative laboratory examinations.
