甲状腺功能减退非缓慢性心律失常的常见病因，其引起的缓慢性心律失常常表现为窦性心动过缓或Ⅰ度房室传导阻滞，引起高度房室传导阻滞较为罕见。本文回顾性分析了13例甲状腺功能减退致间歇性高度房室传导阻滞患者的临床资料，就其机制、临床表现和治疗进行了探讨，认为甲状腺功能减退致间歇性高度房室传导阻滞的治疗应以积极改善甲状腺功能为主，并动态观察心律，可取得良好预后。%Hypothyroidism is an uncommon cause for chronic arrhythmia,and it often manifests as tachycardia or first- degree atrioventricular block,and it is rare in causing high degree atrioventricular block. The paper made a retrospective analysis of 13 cases of intermittent high degree atrioventricular block induced by hypothyroidism and investigated the mechanism, clinical manifestations and treatment of the disease. We suggested that the patients with intermittent high degree atrioventricular block caused by hypothyroidism should be primarily given active treatment to improve thyroid function and the rhythm of heart should be dynamically observed,so that favorable prognosis could be generated.
