BACKGROUND There are currently several electrocardiographic algorithms to locate the accessory pathway (AP) in patients with Wolff-Parkinson-White (WPW) syndrome. OBJECTIVE To compare the ability of electrocardiographic algorithms in identifying the location of the AP in patients with WPW pattern referred for ablation. METHODS Observational, cross-sectional, retrospective study with 111 pat...

Background: Radiofrequency (RF) catheter ablation is an effective method of treatment of patients with WPW syndrome. The purpose of this study was to analyze the initial and follow -up results of RF ablation of such cases in our hospital. Methods: 255 cases with WPW syndrome that had delta wave in sinus rhythm ECG underwent electrophysiological studies in this hospital. All the cases underwent ...

Barrett's esophagus is an area of great interest in Gastroenterology, with an increasing number of research studies being published in recent years and decades. Due to the fast growing evidence regarding this disease, it has become extremely difficult to keep updated on this subject. The present review article aims to summarize and update what is known regarding diagnosis and therapy in Barrett...

OBJECTIVES This study was performed to evaluate the usefulness of temperature-guided radiofrequency catheter ablation for the elimination of accessory pathway conduction in patients with Wolff-Parkinson-White syndrome. METHODS Temperature-guided radiofrequency catheter ablation was attempted in 138 patients with 144 accessory pathways (88 pathways along the left free wall, 5 in the anterosept...

The ventricular pre-excitation syndrome (Wolff-Parkinson-White syndrome) is defined as a premature activation of the entire ventricular myocardium by a super-ventricular impulse. The premature activation is made by accessory conduction pathways that produce a short circuit in the normal nodo-hisian pathway. The accessory pathways are made of atrial myocardial fibers that have a higher conductio...
