摘要
背景:已有报道指出,在复杂心房碎裂电位引导下施行房颤(AF)射频导管消融可消除大部分患者的AF。但是,先前的研究仅包含很少的慢性AF患者。方法和结果:100例慢性AF患者(平均年龄57±11岁)
BACKGROUND -Radiofrequency catheter ablation of atrial fibrillation(AF) guided by complex fractionated atrial electrograms has been reported to eliminate AF in a large proportion of patients. However,only a small number of patients with chronic AF have been included in previous studies. METHODS AND RESULTS -In 100 patients(mean age,57± 11 years) with chronic AF,radiofrequency ablation was performed to target complex fractionated atrial electrograms at the pulmonary vein ostial and antral areas,various regio...
