Pulmonary Vein Isolation
"1. Pulmonary vein isolation (PVI) is performed as the primary procedure.~2. After PVI, direct current (DC) cardioversion is performed to restore normal sinus rhythm. If the patient converts to sinus rhythm, they are randomly assigned to either the PVI-only group or the additional left atrial posterior wall ablation group.~3. Patients who fail to convert to sinus rhythm after DC cardioversion are excluded from randomization."
Additional Left Atrial Posterior Wall Ablation
"1. Additional left atrial posterior wall ablation is performed.~2. Complete electrical isolation of the entire left atrial posterior wall is confirmed (posterior box lesion isolation must be achieved).~3. Post-procedural rhythm monitoring follows the study protocol."
Non-PV trigger test
"1. If atrial fibrillation triggers are identified with isoproterenol infusion, additional focal ablation is performed.~2. Post-procedural rhythm monitoring follows the study protocol."
