Abstract

Objective: The study aims to describe the origin sites and evaluate the outcomes of radiofrequency (RF) ablation for atrial tachycardia over a 5-year period. Methods: The study was conducted on 43 patients diagnosed with atrial tachycardia, who underwent RF ablation treatment from September 2019 to September 2024 at E Hospital. Results: The two main mechanisms of atrial tachycardia were focal atrial tachycardia (56%) and atrial flutter (44%). Most atrial tachycardias originated from the right atrium (76.7%), with the highest occurrence at the tricuspid annulus (27.9%) and the coronary sinus ostium (20.9%). The average follow-up period was 30.5 months, with an early success rate of 88.3% and a success rate after follow-up of 79.0%. The atrial flutter group had a higher success rate than the focal atrial tachycardia group. No complications were observed. Left ventricular ejection fraction (EF) was associated with the recurrence of atrial tachycardia after RF ablation (OR: 1.15; CI: 1.034 – 1.297; p<0.05). Conclusion: Focal atrial tachycardia was more common than atrial flutter, with the majority originating from the right atrium, particularly the tricuspid annulus and the coronary sinus ostium. RF ablation showed high success rates and low complication rates.
