Comparison of the catheter ablation outcome in patients between targeting the entrance and exit of the reentry circuit in verapamil-sensitive atrial tachycardia originating from the atrioventricular-node vicinity

Discrimination of atypical atrioventricular nodal reentrant tachycardia from atrial tachycardia by the V‐A‐A‐V response

“…Since its original clinical description, 10 over 20 studies of ATP‐sensitive AT‐HB have been published worldwide in peer‐reviewed, medical journals 32–51 . In most of these studies, this AT was diagnosed in accordance with the original report 10 .…”

Target potential for ablation in adenosine-sensitive atrial tachycardia originating from the vicinity of the atrioventricular node identified by the LUMIPOINT software

“…The ablation procedure targeting the entrance site of the SCZ was recognized as a safer and more effective therapeutic technique than ablation at the EAAS. 6 However, the precise location of the SCZ and entrance site in AVN-AT remains uncertain, posing a potential risk of AV block during ablation. Sakai and colleagues 7 presented a case of AVN-AT in which manifest entrainment could not be observed at various sites of the right atrium, except for the noncoronary aortic sinus (NCS).…”
