Hyperthyroidism is a prevalent cause of atrial fibrillation (AF). High cardiac output with low systemic vascular resistance, driven by hyperthyroidism, is associated with a rapid heartbeat, enhanced left ventricular systolic and diastolic function, and a higher incidence of supraventricular tachyarrhythmias. After returning to euthyroid status, hyperthyroidism-induced AF generally spontaneously reverts to sinus rhythm (SR), and a significant number of patients remain in chronic AF and require electrical cardioversion (ECV). After effective cardioversion, the long-term outcome of hyperthyroidism-induced persistent AF is unknown. Early ECV before the antithyroid medication should be explored for hyperthyroidism-induced AF to reduce the risk of thromboembolic consequences. The recurrence rate of AF between Hyperthyroid and Euthyroid Patients after ECV did not significantly differ. This review article compares the recurrence rate of AF as an outcome of ECV in Hyperthyroid induced atrial fibrillation.
甲状腺功能亢进是心房颤动（AF）的常见病因。由甲状腺功能亢进驱动的高心输出量和低体循环血管阻力与心跳加快、左心室收缩和舒张功能增强以及室上性快速心律失常的发生率较高有关。恢复到甲状腺功能正常状态后，甲状腺功能亢进引起的房颤通常会自发恢复为窦性心律（SR），并且相当数量的患者会持续处于慢性房颤状态，需要进行电复律（ECV）。有效复律后，甲状腺功能亢进引起的持续性房颤的长期预后尚不清楚。对于甲状腺功能亢进引起的房颤，应探索在抗甲状腺药物治疗前尽早进行电复律，以降低血栓栓塞后果的风险。甲亢患者和甲功正常患者电复律后房颤的复发率无显著差异。这篇综述文章比较了甲状腺功能亢进引起的心房颤动患者电复律后房颤的复发率。
