探讨在三维电解剖标测系统（CARTO）指导下经导管射频消融治疗心房颤动（房颤）的安全性和有效性。
Objective To evaluate the safety and efficacy of radiofrequency catheter ablation guided by 3-dimensional electroanatomic mapping system (CARTO)in treatment of patients with atrial fibrillation (AF).
在心动过速时应用CARTO系统标测相关心房，实时重建三维电解剖图，并用以指导射频放电消融靶点。
During tachycardia, three-dimensional electroanatomical map of the atrium of interest was created using CARTO system, and under its guidance radiofrequency(RF) pulses were delivered.
