Abstract
Objective To investigate the factors for tachycardia recurrence after radiofrequency catheter ablation(RFCA) of accessory pathway(AP). Methods Five hundred and thirty patients with atrioventricular reentrant tachycardia after RFCA were followed up for 7.6 ± 3.2 years. Their electrophysiological data were retrospectively analyzed. Results Tachycardia recurred in 22 of the 530 patients with a total recurrent rate of 4.1%. The recurrent rate was 8.0% in the first 150 patients and 2.6% in the remaining 380 patients (P＜0.05). Tachycardia recurred in some patients 2 years after RFCA. The recurrence of tachycardia was not related with the location and antegrade conduction of AP, but related with the fusion extent of target ventricular and atrial wave, the time to block of AP conduction from the onset of RF current application, and multiple Aps. Tachycardia recurred in some patients due to atrioventricular node reentrant tachycardia rather than the recovery of AP conduction. Conclusion Inaccuracy of ablation target and the presence of multiple Aps may lead to recurrence of tachycardia after RFCA of AP.关键词
