  "abstract": "Background Atrial fibrillation (AF) constitutes a growing public health challenge. Consequently, the exploration of modifiable risk factors is essential for advancing AF prevention and management. While obstructive sleep apnoea is established as a risk factor for AF recurrence following catheter ablation, and its treatment with continuous positive airway pressure therapy reduces recurrence rates, the influence of non-sleep apnoea-related sleep indicators remains unclear. This systematic review aims to elucidate the association between these non-sleep apnoea-related sleep indicators and AF recurrence to inform optimised management strategies.Methods and analysis A comprehensive search will be performed in databases, including PubMed, Embase, the Cochrane Library, Chinese National Knowledge Infrastructure, VIP Database and Wanfang Data, covering publications from database inception to 27 August 2024. Study selection will be performed independently by two reviewers using predefined eligibility criteria, with the screening process documented in a referred Reporting Items for Systematic Review and Meta-Analysis-compliant flow diagram. Data will be extracted using standardised forms and risk of bias of included studies will be assessed with the Risk Of Bias In Non-randomised Studies-of Interventions tool. Non-sleep apnoea-related sleep indicators, including sleep duration, sleep quality, sleep latency, sleep efficiency, REM (Rapid Eye Movement)/NREM (Non-Rapid Eye Movement), etc, serve as exposure factors. The primary outcome is defined as AF recurrence, whereas the secondary outcome comprises quality of life measures among AF patients. Should sufficient data be available, a meta-analysis will be performed using appropriate statistical methods; otherwise, a narrative synthesis will be conducted.Ethics and dissemination This study uses publicly available data, so ethical approval is not required. The findings will be disseminated through peer-reviewed journals and scholarly platforms to inform clinical practice and future research.PROSPERO registration number CRD42024607124.",
