Research progress in cardiac autonomic nerve ablation in the treatment of bradycardia
Bradycardiac arrhythmias are characterized by prolonged RR intervals resulting from various etiologies,and in some cases cardiovascular reflex inducements trigger functional bradycardia or delayed or interrupted conduction.Severe cases may present syncope,also known as cardiac inhibitory vasovagal syncope(VVS).Over the past two decades,rapid advancements in ganglionated plexi(GP)ablation have demonstrated its efficacy in treating VVS and associated bradycardia.Factors influencing the success rate of GP ablation include specific ablation site,GP localization,surgical technique,assessment of ablation endpoint,and integration of other interventions.This article reviews the latest advancements in GP ablation treatment for VVS and bradycardia.
