“…In addition, AF triggered by PV ectopy during AVNRT has also been described 9 and likely explains why some patients with AVNRT present with recurrent AF after successful slow-pathway modification. 7,8 In the present study, we report AVNRT as an isolated trigger of AF in addition to its coexistence with PV and non-PV triggers of AF. In fact, AF triggers were seen in just over half of the patients with AF and AVNRT in the present study.…”

“…In a separate study, Delise et al 7 reported an AF cure rate of 70% of patients presenting with both AVNRT and AF with slow-pathway modification alone. In addition, AF triggered by PV ectopy during AVNRT has also been described 9 and likely explains why some patients with AVNRT present with recurrent AF after successful slow-pathway modification.…”

“…[1][2][3][4] Although the most common sites of atrial ectopy that trigger AF are in or around the pulmonary veins (PVs), rapid atrial activity from other sites can also initiate AF, as can atrioventricular nodal reentrant tachycardia (AVNRT). [5][6][7] In addition, AF often coexists with AVNRT, and AVNRT may trigger remote atrial ectopy that, in turn, initiates AF. [7][8][9] If AVNRT plays a role in AF initiation in a particular patient, elimination of this tachycardia is likely required for the success of catheter ablation of AF.…”

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 and AF, 629 consecutive patients referred for catheter ablation between November 1998 and March 2005 were studied. Electrophysiological studies with programmed stimulation during isoproterenol infusion identified atrial ectopy that initiated AF and the presence of inducible AVNRT. AF ablation consisted of proximal isolation of PVs and elimination of any non-PV trigger of AF, including AVNRT. There were 27 patients (4.3%) who had inducible AVNRT at the time of AF ablation. Of these, 13 underwent AVNRT ablation without PV isolation. Compared with the rest of the cohort, patients with AVNRT and AF were younger at the time of symptom onset (age 36.8Ϯ13.8 versus 48.2Ϯ11.7 years; PϽ0.01). Freedom from AF with or without previously ineffective antiarrhythmic medication was similar in both groups (96.3% versus 90.7%; mean follow-up 21.4Ϯ9.4 months); however, patients with AVNRT targeted for ablation were more likely to be AF free while not taking any antiarrhythmic medication after a single procedure during the follow-up period (87.5% versus 54.7%; PϽ0.01) and had fewer complications (0% versus 2.5%; Pϭ0.30). Twelve of the 13 patients who underwent slow-pathway ablation without left atrial ablation remained AF free without the need for antiarrhythmic medication after a single procedure. Conclusions-AVNRT

“…It is known that patients with Wolff-ParkinsonWhite syndrome have a higher incidence of atrial fibrillation than the rest of the population 15 and that the elimination of the accessory pathway using ablation techniques also generally suppresses atrial fibrillation. tachycardia caused by nodal reentry have a higher incidence of atrial fibrillation 16 , and the frequency of crises can be reduced after elimination of tachycardia 17 . Recently, we have observed that in some patients a focus of very rapidly occurring atrial tachycardia can lead to atrial fibrillation.…”
