PURPOSE The aim of the present study was to evaluate the characteristics of electrophysiologic studies (EPS) and radiofrequency ablation (RFA) performed in subjects aged less than 30 years with Wolff-Parkinson-White (WPW) syndrome, particularly pediatric patients under 18 years of age, based on our experience. METHODS Two hundred and one consecutive patients with WPW syndrome were recruited a...

BACKGROUND PRKAG2 syndrome diagnosis is already well-defined as Wolff-Parkinson-White syndrome (WPW), ventricular hypertrophy (VH) due to glycogen accumulation, and conduction system disease (CSD). Because of its rarity, there is a lack of literature focused on the treatment. The present study aimed to describe appropriate strategies for the treatment of affected family members with PRKAG2 synd...

In four patients with WPW syndrome atrial and ventricular premature beats were induced and the changes in form of the ventricular and atrial complexes were studied. Results indicate that, depending upon the timing of the premature atrial beat and the state of refractoriness of the His and Kent bundles, excitation of the ventricles occurs predominantly through the atrioventricular nodal system, ...

Abstract Introduction Atrioventricular nodal reentry tachycardia (AVNRT), Wolf-Parkinson-White syndrome (WPW), and Ectopic atrial (EAT) are common arrhythmias associated with lower quality of life. The use radiofrequency ablation (RFA) treatment has increased over time, however long-term risk adverse outcomes after RFA in patients AVNRT, WPW, or EAT is unknown. Purpose To examine the need for p...

To the Editor: n volume 2, No. 3 (2014) of this journal an interesting case report, describing a patient with atrial filbrilla-tion (AF) and Wolff-Parkinson-White syndrome (WPW), was published (1). As the respective authors described , the patient was a 23-year-old man who had palpitation , on the Electrocardiograph (ECG), which was provided, we saw irregular monomorphic wide complex tachycardi...

Background Epidemiological data indicate that 0.1% to 0.3% of the general population have ECG findings suggesting that during sinus rhythm, in addition to AV conduction over the AV node His pathway, there is also AV conduction over an accessory AV pathway (AP).4 This means that each year 4 new cases are found in a population of 100 000. It is also known that there is a 4-fold increase of this f...

Since the advent of catheter ablation for atrial fibrillation (AF) aiming the pulmonary veins a few years ago, there has been an overwhelming interest and a dramatic increase in AF investigation. AF has a different dimension in the context of the Wolff-Parkinson-White (WPW) syndrome. Indeed, AF may be a nightmare in a young person that has an accessory pathway (AP) with fast anterograde conduct...

Among patients with a Wolff–Parkinson–White (WPW) syndrome, approximately half will experience arrhythmia during their lifetime. Radiofrequency catheter ablation of the accessory atrioventricular pathway is the treatment of choice for this condition and is associated with a high success rate. Electrophysiology study is indeed the key procedure for identifying the target of radiofrequency ablati...

BACKGROUND Atrial fibrillation (AF) in patients with Wolff-Parkinson-White syndrome (WPW) may induce complex ventricular arrhythmias resulting in sudden cardiac death. It is essential to find an effective non-invasive diagnostic method allowing to select patients at risk of life-threatening arrhythmias. Our objective was to examine Doppler predictors of AF in patients with WPW and atrioventricu...
