Different Catheter Ablation Strategy in Vasovagal Syncope

This study is a prospective, single-center randomized controlled clinical trial. patients with refractory vasovagal syncope were randomly divided into two groups according to the proportion of 1:1. Group A: simple left atrial ganglion plexus ablation (RAGP + LSGP + LLGP + LIGP + RIGP ablation); B group: left atrial ganglion plexus combined with right atrial ganglion plexus ablation (group A + consolidation ablation of RAGP at the junction of right atrial septum and superior vena cava). To clarify the role of RAGP in cardiac autonomic nervous system and the effect of ablation, to establish the standard stragtegy of cardiac nerve ablation.
