Atrioventricular Nodal Reentrant Tachycardia in Patients Referred for Atrial Fibrillation Ablation

Atrioventricular nodal reentrant tachycardia in patients referred for atrial fibrillation ablation: response to ablation that incorporates slow-pathway modification.

BACKGROUND Although the most common sites of atrial ectopy that trigger atrial fibrillation (AF) are in or around the pulmonary veins (PVs), atrioventricular nodal reentrant tachycardia (AVNRT) can also cause or coexist with AF. We sought to characterize patients with AF and AVNRT and assess clinical outcomes after ablation. METHODS AND RESULTS To determine the prevalence of concomitant AVNRT...

Atrioventricular nodal block with atrioventricular nodal reentrant tachycardia ablation.

Suppression of atrial fibrillation following successful ablation of atrioventricular nodal reentrant tachycardia: a case report.

Inducible atrioventricular nodal reentrant tachycardia was demonstrated by electrophysiological studies in a 55-year-old female who suffered from intermittent palpitation, in which paroxysmal atrial fibrillation (AF) was consistently documented by electrocardiogram recordings. After ablation of the slow pathway, the atrioventricular nodal reentrant tachycardia and AF were not inducible. During ...

Left Septal Slow Pathway Ablation for Atrioventricular Nodal Reentrant Tachycardia.

BACKGROUND Immunohistochemistry studies suggest that the anatomic substrate of the slow pathway in atrioventricular nodal reentrant tachycardia (AVNRT) is the left inferior nodal extension. We hypothesized that slow pathway ablation from the left septum is an effective alternative to right-sided ablation. METHODS AND RESULTS We analyzed our databases of AVNRT in search of cases that had used ...
