Figure 1: Syncopal events. A) Pre-cardioneuroablation
(CNA) syncope: The patient’s implantable loop recorder (ILR) recorded
gradual sinus slowing followed by 13 seconds of sinus arrest with
asystole, causing syncope. B) Post-CNA syncope: 7 months after
successful CNA, the ILR recorded gradual sinus slowing leading to
junctional beats followed by 7 seconds of sinus arrest with asystole,
causing syncope.
