Brief Summary:
In this study, the investigators aim to examine the prognostic role of subsequent Atrial Tachycardias (ATs) in the mechanisms of atrial fibrillation (AF). Therefore, the investigators compare patients who were randomly assigned to either undergo cardioversion after AF has been terminated to AT or further ablation until the achievement of sinus rhythm.

Condition or disease Intervention/treatment
Atrial Fibrillation Procedure: Catheter ablation of subsequent atrial tachycardia

Study Type : Observational
Actual Enrollment : 110 participants
Observational Model: Case Control
Time Perspective: Prospective
Official Title: The Prognostic Role of Subsequent Atrial Tachycardias Occurring After Atrial Fibrillation Termination: A Prospective Randomized Trial
Study Start Date : June 2009
Actual Primary Completion Date : March 2013

Group/Cohort Intervention/treatment
Group A: cardioversion at AT
after achievement of AT, pts were cardioverted
Group B: ablation to SR
After AT has been achieved, all subsequent AT were ablated with the endpoint of procedural SR termination
Procedure: Catheter ablation of subsequent atrial tachycardia

Primary Outcome Measures :
  1. Arrhythmia-free survival [ Time Frame: 24 months after enrolment ]

Secondary Outcome Measures :
  1. Type of Arrhythmia recurrence [ Time Frame: 24 months after enrolement ]

Other Outcome Measures:
  1. Time to recurrence [ Time Frame: after blanking period (3 months) until study end (at least 24 months) ]
