Prospective Randomized Study on Clinical Effectiveness of Carvo-Tricuspid Isthmus (CTI) Block in Patients with Paroxysmal Atrial Fibrillation (PAF) will be performed. Study will be composed with two arms including 4 pulmonary vein isolation and pulmonary vein isolation with CTI block. After that all patients will be followed up by HRS(Heart Rhythm Society) 2010 expert consensus guideline.
