Brief Summary
The purpose of the study is to investigate whether or not there are the differences in acute procedure and long-term clinical outcome of radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) using the 3D map constructed by the integration of CT(or MRI) with the fast anatomical mapping (FAM) versus using the 3D map constructed by FAM only.
