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 Intervention
Atrial Fibrillation
Procedure: Catheter ablation of subsequent atrial tachycardia

Study Type: Observational
Study Design: 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

Primary Outcome Measures:
  • Arrhythmia-free survival [ Time Frame: 24 months after enrolment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Type of Arrhythmia recurrence [ Time Frame: 24 months after enrolement ] [ Designated as safety issue: No ]

Other Outcome Measures:
  • Time to recurrence [ Time Frame: after blanking period (3 months) until study end (at least 24 months) ] [ Designated as safety issue: No ]

Enrollment: 110
Study Start Date: June 2009
Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
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
