Atrial fibrillation (AF) is the most common arrhythmia in cardiovascular disease, and it often coexists and interacts with sick sinus syndrome. In the past, pacemaker implantation combined with antiarrhythmic drugs was preferred for symptomatic atrial fibrillation with long interval treatment. However, in recent years, more and more studies have shown that compared with pacemaker implantation, radiofrequency ablation can reduce the hospitalization rate related to tachycardia, effectively control atrial fibrillation, and improve patient prognosis and hospitalization rate of heart failure. However, some patients present intrinsic sinus node dysfunction (SND), and SND may progress and worsen in some patients with atrial fibrillation. Therefore, the first-line treatment strategy for patients with atrial fibrillation with long interval remains controversial. This article reviews the selection of long-term intermittent treatment strategies for atrial fibrillation.

心房颤动（房颤）是心血管疾病中最为常见的心律失常，其常与病态窦房结综合征并存且相互作用。既往临床上对于有症状的房颤伴长间歇治疗多倾向于植入心脏起搏器联合抗心律失常药物，但近年来越来越多的研究表明，与植入起搏器相比，射频消融能降低房性心动过速相关心律失常的住院率、有效控制房颤，改善患者预后及心力衰竭住院率。但同时部分患者存在固有窦房结功能障碍（SND），且SND可在部分患有房颤的患者中逐渐进展及加重。因此，房颤伴长间歇患者的一线治疗策略仍存在争议。本文以房颤伴长间歇治疗策略的选择进行综述。
