Abstract

Background: Atrial tachycardia (AT) is a commonly encountered rhythm disorder and most patients require catheter ablation. In this study, the aim was to evaluate the outcomes of catheter ablation in patients with symptomatic AT, define acute and long-term outcomes, and determine the clinical and electrophysiological features that affect these outcomes. Methods: A total of 666 (mean age: 55 ± 16, gender: 344 (51.7 Results: Macroreentry was the primary mechanism in right and left atrium (70.2 Conclusion: The findings demonstrated that catheter ablation of tachycardia has a high acute success rate and favorable long-term outcomes in patients with symptomatic AT.
