Comparison Between Contact Force Guided and Blinded Strategy on PV Isolation in AF Patients
Atrial Fibrillation
About this trial
This is an interventional treatment trial for Atrial Fibrillation focused on measuring pulmonary vein isolation, contact force sensing catheter
Eligibility Criteria
Inclusion Criteria:
- Patients with symptomatic paroxysmal atrial fibrillation (AF) who had failed with anti-arrhythmic agents.
Exclusion Criteria:
- Patients who had previous ablation for AF
- Patients with symptomatic persistent AF

Fifteen patients will be allocated to this group. Left side pulmonary veins isolation will be performed with contact force information guidance. Then, right side pulmonary veins isolation will be performed without contact force information (using same catheter named SmartTouch Catheter).
