近年来,肿瘤治疗相关心律失常的发病率逐年增多.肿瘤患者心律失常的发生率明显高于正常人群,肿瘤与心律失常发生具有极其紧密的联系.肿瘤治疗相关QT间期延长综合征、心房颤动等心律失常增加了肿瘤患者的死亡率.肿瘤导致心律失常可能与肿瘤相关治疗引起的心脏毒性作用相关.因此,加强对肿瘤相关心律失常的具体原因及机制的研究,及时预防肿瘤相关心律失常的发生,对提高肿瘤患者的生存率具有极其重要的意义.“,”In recent years,the incidence of cancer-related arrhythmia has increased year by year.The incidence of arrhythmia in cancer patients was significantly higher than that in normal people,and the tumor is closely related to arrhythmia.The mortality of cancer patients were increased because of arrhythmias,such as tumor therapy-related QT prolongation syndrome,atrial fibrillation and so on.Tumor-induced arrhythmias may be related to the cardiotoxic effect of tumor-associated therapies.It is extremely important that studying the causes and mechanisms of tumor-specific arrhythmia and preventing the occurrence of tumor-related arrhythmias for improving the survival rate of cancer patients.
