Clinical Electrophysiological Features and Radiofrequency Ablation of Patients with Atrial Fibrillation

Abstract

This study aimed to investigate electrophysiological features of radiofrequency ablation surgery in patients with the atrial fibrillation (AF). Fifty patients were included in this study and evenly divided, with 25 AF patients in the experiment group and 25 patients with arrhythmias in the control group. General clinical materials in the two groups were collected. Then, patient number of pulmonary vein antrum potential trial, intra-right atrial conduction time, intra-left atrial conduction time, interatrial conduction time, conduction time between atrium, and pulmonary veins trials were utilized to measure the efficacy of radiofrequency ablation surgery in patients with AF and clarify the relationship between AF and electrophysiological features in the atrium and pulmonary veins. Our study findings showed that conduction time interval between the atrium and pulmonary veins trial by radiofrequency ablation surgery were significantly less than those in pre-treatment AF patients. We can conclude that radiofrequency ablation surgery can effectively treat AF patients by relieving the electrophysiological dysfunction, and radiofrequency ablation can be used to prevent the development of AF.
