Abstract

A 65-year-old woman presented to the emergency room with a syncope. An ECG done revealed complete heart block with a narrow QRS escape rhythm and a normal QT interval. Further investigation revealed severe hypercalcaemia and elevated parathormone levels. Her heart block disappeared on correction of the hypercalcaemia. A right inferior parathyroid adenoma was found and surgically removed. Thus, hypercalcaemia may lead to reversible complete heart block without QT interval shortening.

摘要

一位 65 岁女性因晕厥到急诊就诊。心电图显示完全性心脏阻滞，伴有窄 QRS 逸搏节律和正常 QT 间期。进一步检查发现严重高钙血症和甲状旁腺激素水平升高。高钙血症纠正后，心脏阻滞消失。发现右侧下甲状旁腺腺瘤，并进行了手术切除。因此，高钙血症可能导致无 QT 间期缩短的可逆性完全性心脏阻滞。
