Abstract

Background: Radiofrequency catheter ablation is an effective method of complete treatment for most patients. Objectives: To study on electrophysiological characteristics and results of radiofrequency ablation therapy in patients with paroxysmal supraventricular tachycardia (PSVT) dependent on the atrioventricular node. Materials and methods: Descriptive cross-sectional study, we conducted on 57 patients with surface electrocardiogram as PSVT on the atrioventricular node who came for examination and treatment at An Giang Heart Hospital from 1/2021-5/2022. All patients underwent electrophysiology study and were treated with radiofrequency ablation. The time of follow-up was one month about the complications and recurrence. Results: In our study, the mean age was 48.95±13.88 (15-73). Females accounted for the majority with 38 patients (66.7%), and the male was 19 patients (33.3%). The frequency of atrioventricular node reentry tachycardia was 38 (64.41%) and atrioventricular reentry tachycardia was 21 (35.59%). The success rate of the procedure was 100%. In the study, there were 3 patients (5.26%) with mild complications such as hematoma at the puncture site and reversible atrioventricular block. There were no serious complications or death. Only 1 patient (1.75%) recurred after ablation. Conclusions: The results of our study show that the electrophysiology study was an accurate method of diagnosing PSVT dependent on the atrioventricular node. Treatment with radiofrequency catheter ablations had a high success rate, low complication rate and mild. The recurrence rate was very low.
