Background: Obstructive sleep apnea (OSA) has been associated with many forms of heart rhythm disorders, including bradycardia and cardiac conduction delay. Here, we aimed to investigate the relationship between OSA bradyarrhythmias. Methods: A retrospective cohort study was conducted using Nationwide Inpatient Sample from 2016 2020. 1,685,704 hospitalizations a primary diagnosis bradyarrhythmias (including sinus node dysfunction, atrioventricular block disorder 1:1 AV conduction) were identified stratified based on presence ICD-10 codes. Multivariate regression analysis used adjust for confounders analyze variables. Results: Out bradyarrhythmias, 204,307 (%12.1) had OSA. In-hospital mortality in patients significantly lower (3.51% vs 5.64%; p<0.001). When adjusted patient demographics, comorbidities, hospital characteristics, independent risk factors inpatient included congestive failure (aOR 1.22, 95% CI 1.17 - 1.27, p-value<0.001), atrial fibrillation 1.14, 1.10 1.18, p-value <0.001); however conditions previous CABG 0.91, 0.85 0.97, 0.004) pacemaker 0.61, 0.58 0.65, <0.001). Mean length stay (LOS) mean charges (HC) also obstructive compared those without (5.28 6.01 days, 0.002 & $90,549 $103,450, < 0.001 respectively). Conclusion: Amongst better outcomes terms in-hospital mortality, total hospitalization charges. This likely suggests that OSA-related are more benign modifiable when non-OSA-related
