We present the case of a 82-year-old woman with a history of total thyroidectomy who was admitted in hospital with severe hypocalcemia. A 12-lead surface ECG revealed atrial fibrillation along with an extremely prolonged QT interval of approximately 730ms. In the absence of any other possible cause of QT interval prolongation, hypocalcemia was attributed to surgical hypoparathyroidism and undue discontinuation of calcium supplementation. Surprisingly, no ventricular arrhythmias were recorded and calcium repletion was followed by normalization of QT interval.
我们报告一例82岁女性患者，有甲状腺全切术病史，因严重低钙血症入院。12导联体表心电图显示房颤，QT间期极度延长，约为730毫秒。在没有任何其他可能导致QT间期延长的原因的情况下，低钙血症归因于手术导致的甲状旁腺功能减退以及不当停用钙剂。令人惊讶的是，未记录到室性心律失常，补充钙剂后QT间期恢复正常。
