Although some studies suggest that sarcopenia may be associated with an increased risk of atrial fibrillation (AF), the evidence supporting this association remains insufficient. This study aims to systematically evaluate existing clinical research to explore the relationship between sarcopenia and atrial fibrillation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A systematic search was conducted of relevant literature in the PubMed, Embase, Cochrane Library, and Web of Science databases. The search period ranged from the establishment of the databases to May 15, 2025. Inclusion criteria were observational studies that explored the relationship between sarcopenia and atrial fibrillation. All included studies will be assessed for quality using the Newcastle-Ottawa Scale (NOS) to evaluate the quality of study selection, comparison, and results, ensuring the reliability of the analysis results. The data for this study will be analyzed using Stata 15.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 6 studies involving 3,067,241 patients, Meta-analysis results suggest that sarcopenia is associated with a higher likelihood of developing AF compared to patients without sarcopenia [OR\u202f=\u202f2.16, 95% CI (1.80, 2.60)].
