OBJECTIVE To describe the mode of presentation and the clinical course of patients with ventricular pre-excitation (Wolff-Parkinson-White (WPW) syndrome), with special emphasis on asymptomatic cases in the general population. METHODS Over an eight year period (1990-97) a prospective population based survey of cases with WPW pattern was conducted in a defined population in north west Greece (3...

Twenty-six patients with Wolff-Parkinson-White (WPW) syndrome were studied by echocardiography. They were classified into the following WPW types: anterior right ventricular pre-excitation (Type I) - six patients; posterior right ventricular pre-excitation (Type II) - six patients; posterior left ventricular pre-excitation (Type III) - fourteen patients. Twenty-three patients were in WPW at the...

Electrophysiological studies were performed in five patients, two with the three without Wolff-Parkinson-White (WPW) syndrome. In the former patients group, the paroxysmal supraventricular tachycardia (PSVT) was concluded to reflect the circus movement utilizing the normal atrioventricular (A-V) conduction system for antegrade conduction and the Kent bundle for the retrograde conduction. Ventri...

Wolff-Parkinson-White (WPW) syndrome is a type of pre-excitation syndromewhere part cardiac ventricles are activated too early by virtue an accessory pathway, that directly attaches atria and ventricles, thereby allowing electrical activity to bypass AV node, thus leading episodes tachycardia which can be either asymptomatic or may present with dyspnoea on exertion palpitation. As it’s rare con...

Wolff-Parkinson-White syndrome (WPW) is a congenital syndrome with an increased risk of malignant tachyarrythmias and sudden cardiac death [1]. Inappropriate treatment of this syndrome peri-operatively can quickly cause clinical deterioration[2]. Unfamiliarity with this rare condition (0.1–0.3% of population)[3] and difficult resuscitation in the prone position could further worsen outcomes. WP...

Recurrent or incessant tachycardia is frequently found in symptomatic Wolff-Parkinson-White (WPW) syndrome, leading to ventricular dysfunction, dilated cardiomyopathy (DCM) and heart failure in infants and children. Recently, Winter, et al. report that WPW syndrome could provoke many kinds of cardiac dysfunction, leading to remodeling and progressive ventricular dilatation through pre-excitatio...
