Kết quả thăm dò điện sinh lý và triệt đốt bằng sóng tần số radio ở các bệnh nhân rối loạn nhịp trên thất tại Bệnh viện Trung ương Quân đội 108 từ năm 2018 đến năm 2020

Abstract

Objective: To study the clinical characteristic of supraventricular tachycardia and efficacy of radiofrequency (RF) ablation. Subject and method: A retrospective, descriptive study was performed on 331 supraventricular patients, atrial fibrillation, flutter patients and patients suspected of supraventricular arrythmias. All the data were taken from case notes, type of arrhythmias, success rate and complication were recorded. Result: AVNRT (Atrioventricular nodal reciprocal tachycardia) took up 31.7%, Accessory pathway tachycardia was of 22.6% and atrial tachycardia (AT) took up 5.7%. Of which, for concealed accessory pathway, left sided accessory pathway was found on 80%, right sided accessory pathway was seen in 20%. Success rate were of 99%, 97.1%, 95%, 68.4% for AVNRT, WPW syndrome, concealed accessory pathway; AT, respectively. Advanced A-V block was seen in 0.4%. Conclusion: RF ablation for supraventricular tachycardia was an effective method with high success rate, low complication and low recurrent rate.
