Predictive value of the induction test with atrial burst pacing with regard to long-term recurrence after ablation in persistent atrial fibrillation.

ABSTRACT:

Background

Induction test of atrial fibrillation (AF) is one of endpoint measures in catheter ablation (CA). However, its predictive value in long-term outcome remains controversial.

Methods

Ninety-eight patients (61 years, 77 males) with persistent AF who underwent pulmonary vein antrum isolation-based CA were retrospectively analyzed. We determined whether inducibility of AF/atrial tachyarrhythmias (AT) by atrial burst pacing at the end of CA and other characteristics were associated with the recurrence of AF/AT. Atrial burst pacing was performed with 30-beat from the coronary sinus; increasing from 240 to 320 ppm. Inducibility was defined as AF/AT lasting ≥5 minutes following atrial burst pacing.

Results

AF/AT was induced in 50 patients (51%). During 1 year of foll
