The study will analyze radiation dose exposure to key cardiac structures, including the sinoatrial node (SAN) and pulmonary veins (PV), to identify risk factors for atrial fibrillation (AF) and other arrhythmias. Patients will receive wearable CR monitoring at 3, 12, and 24 months post-radiotherapy, with cardiology follow-up and intervention based on standard clinical guidelines. The study will recruit 111 patients over three years, with a two-year follow-up after radiotherapy. The primary endpoint is the incidence of grade 3+ AF within 2 years, with secondary outcomes including any-grade arrhythmia rates, arrhythmia burden, and survival analysis. By establishing a prospective thoracic radiotherapy patient cohort, this study aims to identify dose-related risk factors, improve early detection and management of radiation-induced arrhythmias, and provide evidence-based strategies to enhance treatment safety and efficacy.",[41,42,43,44,45],"Cardiotoxicity","Thoracic Radiotherapy","Wearable Electronic Devices","Thoracic Neoplasms","Atrial Fibrillation","NOT_YET_RECRUITING","2025-04-16",{"date":49,"type":50},"2025-04-18","ACTUAL",{"date":52,"type":37},"2025-05",{"date":54,"type":37},"2030-02-16",{"name":5,"class":6},1]
