慢性心房颤动(简称房颤)经导管消融术后维持窦性心律(简称窦律)的人数占总消融人数的百分率因采取不同的消融策略而有不同,在70%～95%之间。多种指标影响消融术后的临床转归,病程长、左房大、左房疤痕和纤维化、体表ECGf波频率快振幅低、最大P波时程长是预测慢性房颤消融术后复发的危险因素,而年龄、体重指数、结构性心脏病指标报道不一,有待进一步研究。慢性房颤是多因素综合的结果,个体差异很大,应根据上述危险因素综合评分,合理选择患者。
Chronic atrial fibrillation (atrial fibrillation) after catheter ablation to maintain sinus rhythm (referred to as sinus rhythm), the number of the total number of ablation due to take different ablation strategies vary, between 70% to 95%. A variety of indicators affect the clinical outcome after ablation, long course, left atrium, left atrial scarring and fibrosis, ECGF wave velocity on the body surface fast, the maximum length of P wave is the prediction of recurrence of chronic atrial fibrillation recurrence Risk factors, while age, body mass index, structural heart disease indicators reported different, pending further study. Chronic atrial fibrillation is the result of multi-factor synthesis, individual differences are very large, should be based on the above risk factors comprehensive score, a reasonable choice of patients.
