摘　　要：目的:探索心房颤动患者经环肺静脉射频消融术(CPVA)术中转为规则房速的可能影响因素。方法:本研究选取2010年1月-2011年8月厦门市心脏中心首次行经导管心房颤动射频消融手术的房颤患者188例,通过对术中转为规则房速及未转为规则房速患者术前检测的指标包括BNP、EF、LA、LVD、房颤类型等进行分析,探索术中转为房速的可能影响因素。结果:在119例阵发性房颤患者中有33例转为规则房速;持续性房颤患者中有31例转为房速,单因素分析结果显示发生房速组与未发生组BNP、EF、LA比较差异有统计学意义(P=0.001、0.001、0.047),是房颤消融术中转为规则房速的可能影响因素,再将以上三者行二元Logistic多因素回归分析,得出BNP(P=0.027,相对风险度0.999,95%CI0.998～1.000)。结论:BNP可能是房颤消融术中转为规则房速的预测因素。Objective：To explore the clinical predictions of regular atrial tachycardia during circumferential pulmonary vein radiofrequency ablation（CPVA）procedures.Methods：The study involved 188 patients with atrial fibrillation who underwent intial CPVA from January 2010 to August 2011 in the Xiamen heart centre.Univariate analysis and multivariate analysis were carried out to assess the predictive value including BNP、EF、LA、LVD and the kind of atrial fibrillation on the AF by ablation.Results：33 patients converted to regular atrial tachycardia in 119 patients withparoxysmal atrial fibrillation,31 patients of persistent atrial fibrillation coverted to atrial tachycardia,by univariate analysis of 188 patients with atrial fibrillation showed,BNP（P=0.001）,EF（P=0.001）,LA（P=0.047）were predictors of atrial fibrillation converted to regular atrial tachycardia during CPVA.However,only BNP was the independent predictor（P=0.027,RR0.999,95%CI 0.998-1.000）by multivariate analysis.Conclusion：BNP maybe the predictive factors of atrial fibrillation transfer to the regular atrial tachycardia during the ablation.
