A 55 year old woman in thyrotoxic crisis developed atrial fibrillation, atrioventricular block, and sinoatrial block in rapid succession. All of these abnormalities resolved completely after antithyroid treatment. This course of events illustrates the profound effect of thyroid hormones on cardiac function. In view of the potential aggravation of atrioventricular conduction disturbance by beta adrenergic blocking agents, thyrotoxic patients should be carefully screened for electrocardiographic evidence of conduction disturbance before the administration of such drugs.
一名55岁处于甲状腺毒症危象的女性迅速相继出现心房颤动、房室传导阻滞和窦房传导阻滞。抗甲状腺治疗后，所有这些异常均完全消失。这一系列事件说明了甲状腺激素对心脏功能的深远影响。鉴于β肾上腺素能阻滞剂可能加重房室传导障碍，在给甲状腺毒症患者使用此类药物之前，应仔细筛查其心电图是否有传导障碍的证据。
