Paroxysmal atrio-ventricular (AV) block is a relatively rare form of bradyarrhythmia that may be caused by vagal reflex, intrinsic His-Prukinje system (HPS) disorder, or idiopathic mechanisms. We report a case with paroxysmal AV block and syncopal episodes that appeared only during intra-atrial reentrant tachycardia (IART) after an ablation procedure. Syncope did not occur under sinus rhythm with stable 1:1 AV conduction. An HPS disorder was proven in an electrophysiological study. It was suggested that paroxysmal AV block was induced via a tachycardia-dependent mechanism with an exacerbation of latent HPS disorder. The occurrence of the IART was only transient, and there was no recurrent syncope during oneyear follow-up. Pacemaker implantation could be avoided.

“…The PAVB is relatively rare, and due to its transient nature, it is often under‐recognized . Current literature reveals three types of PAVB as associated with syncope (a) intrinsic PAVB (Stokes‐Adams attack type “cardiac syncope”), (b) extrinsic vagal PAVB (“reflex syncope”), and (c) extrinsic idiopathic PAVB (“low‐adenosine syncope”) .…”
