A 51-year-old African male presented to the emergency department with a sore throat, a productive cough and a striking pinched voice. Investigation revealed severe hypocalcaemia (0.97 mmol/l) with a prolonged QT interval on ECG. The authors administered intravenous calcium in the emergency department, which instantly improved the quality of the patient's voice. He was eventually diagnosed with primary hypoparathyroidism and an upper airway infection. Severe hypocalcaemia is a life-threatening condition. Identifying laryngospasm as an atypical presentation in the presence of a concomitant airway infection and prompt treatment in the emergency department are critical.
一名51岁的非洲男性因喉咙痛、咳痰性咳嗽和明显的声音嘶哑来到急诊科。检查发现严重低钙血症（0.97毫摩尔/升），心电图显示QT间期延长。作者在急诊科给予静脉补钙，患者声音质量立即得到改善。他最终被诊断为原发性甲状旁腺功能减退症和上呼吸道感染。严重低钙血症是一种危及生命的疾病。在伴有气道感染的情况下，将喉痉挛识别为非典型表现并在急诊科及时治疗至关重要。
