We present the case of a 46-year-old lady who received an implantable loop recorder for convulsive syncope occurring independent of body position. The device detected asystole lasting more than 11 seconds during recurrence of her symptoms. She refused pacemaker therapy and opted for catheter based vagal denervation through cardioneuroablation. During the procedure the right anterior ganglionated plexus was targeted by radiofrequency ablation from both the left and right atrium. After the procedure she remains free of symptoms during 5 months of follow-up. Her device demonstrated persistently elevated sinus rate after the ablation and a drop in heart rate variability, signifying selective vagal denervation.
