Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Radiofrequency catheter ablation is effective in the treatment of patients with paroxysmal atrial fibrillation. In order to reduce the recurrence rate after catheter ablation, the investigators propose to apply 'virtual' ablation on patient-specific atria by simulating 3D atrial computer model. The investigators will conduct virtual rotor mapping in the patient specific atrial model. Then, the investigators will compare the clinical outcome of conventional circumferential pulmonary vein isolation and additional rotor ablation guided by virtual rotor mapping.
