title: Hypomagnesaemia, cardiac arrhythmias and orthotopic liver transplantation.
abstract: Two patients who underwent orthotopic liver transplantation and developed peroperative cardiac arrhythmias are presented. In one, the arrhythmias were refractory to treatment with anti-arrhythmic drug therapy until serum magnesium levels were restored to normal. The other patient had a low pre-operative serum magnesium level and developed atrial fibrillation on induction of, and during, anaesthesia. Patients undergoing orthotopic liver transplantation may be a group especially predisposed to hypomagnesaemia. The importance of monitoring serum magnesium levels in such patients who develop peroperative cardiac arrhythmias is emphasised.
