Objective: This study aimed to explore the safety and effectiveness of selective cardiac autonomic ganglion plexus (GP) ablation on patients with bradyarrhythmia. The heart is controlled by its own intrinsic and central autonomic nerves. Increased cardiac vagal tone leads to sinus node dysfunction and atrioventricular conduction disorders, resulting in bradyarrhythmia. Pacemaker implantation can relieve the symptoms of arrhythmia caused by bradycardia, but it is not easy for patients to accept a pacemaker implantation as a form of treatment. Therefore, more and more attention has been paid to cardiac vagus nerve ablation. Methods: In this study, 20 patients who met the inclusion criteria of GP ablation in the First Affiliated Hospital of Xinjiang Medical University from November 2019 to June 2020 were enrolled. Biochemical and other related examinations along with electrophysiological examinations were conducted before ablation, and then cardiac GP ablation was performed. The patients were followed up 3 times at 3, 6, and 12 months after the operation. Results: The minimum HR and mean HR were significantly increased after treatment with cardiac autonomic GP ablation (p<0.01). Moreover, the SDNN (Standard deviation of Normal-to-Normal Intervals) and RMSSD (Root mean square successive differences between successive R-R intervals) was significantly decreased after treatment with cardiac autonomic ganglion plexus ablation for 6 months and 12 months (p<0.01). Conclusion: Cardiac GP ablation is relatively simple and easy to implement in units that have performed radiofrequency ablation for bradyarrhythmias. This procedure can be performed without any new equipment. Some patients with bradycardia may not have a permanent pacemaker implantation and may go in for additional treatment options.
