Background—Transient sinus bradycardia and hypotension have been reported as
complications during radiofrequency (RF) ablation of focal atrial fibrillation (AF) originating�…

PV Stenosis after AF Ablation. Introduction: Elimination of the initiating focus within the
pulmonary vein (PV) using radiofrequency (RF) catheter ablation is a new treatment�…

BACKGROUND: Circumferential and segmental pulmonary vein ablations are two
established treatment strategies for ablation of atrial fibrillation. Both techniques require the�…

Introduction: The pulmonary veins (PVs) are a dominant source of triggers initiating atrial
fibrillation (AF). While recent evidence implicates these structures in the maintenance of�…

HRV After AF Ablation by Irrigation Tip Catheter Background Radiofrequency catheter
ablation (RFCA) for atrial fibrillation (AF) changes cardiac autonomic nerve activity�…

Pulmonary Vein Tachycardia. Introduction: The significance of intermittent tachycardia within
a pulmonary vein (PV) during an episode of atrial fibrillation (AF) is unclear. The aim of this�…

Ablation of Focal AF. Introduction: Several reports have demonstrated that focal atrial
fibrillation (AF) may arise from pulmonary veins (PVs). The purpose of this study was to�…

Objective: Radiofrequency (RF) ablation at the ostia of the pulmonary veins (PVs) to cure
atrial fibrillation (AF) is often followed by early AF recurrence. The aims of this study were to�…

Ablation of AF Initiated by PV Ectopic Beats. Ectopic beats from the pulmonary veins (PVs)
have been demonstrated to initiate atrial fibrillation (AF). This article describes the�…

Ablation of Focal Atrial Fibrillation. Introduction: Ablative therapy for atrial fibrillation (AF) by
targeting initiating triggers, usually in or around the pulmonary veins, has been reported by�…
