Abstract：Atrial fibrillation is one of the most common arrhythmias. A large number of studies have shown that tumor and atrial fibrillation share many common risk factors. Tumor progression and anti-tumor therapy can both increase the risk of atrial fibrillation, and the occurrence of atrial fibrillation event during anti-tumor therapy and follow-up can affect the treatment effect and prognosis of tumor patients. Tumor-induced atrial fibrillation may be related to the cardiotoxicity of tumorassociated therapy, increasing the mortality of tumor patients. This paper summarizes a large number of domestic and foreign literatures on the potential mechanism of tumor-induced atrial fibrillation.
