Wpw syndrome

Introduction Wolff-Parkinson-White (WPW) syndrome is a condition that predisposes to supraventricular tachycardia due to an accessory pathway in the heart. Wolff-Parkinson-White syndrome presents with characteristic ECG findings, which may be associated with tachyarrhythmias and clinical symptoms of tachycardia. The accessory pathway in Wolff-Parkinson-White syndrome is a congenital abnormality occurring in 1-3 people per 1000. 1 You might also be interested in our over 1000 flashcards that cover key medical topics. Aetiology In Wolff-Parkinson-White, an accessory pathway leads to stimulation of the ventricles. The accessory pathway enables electrical conduction to bypass the AV node and stimulate the proximal ventricles prematurely (pre-excitation). This, in addition to normal electrical conduction through the AV node, leads to ‘ double excitation’ of the ventricles. The location and conduction through the accessory pathway varies between individuals. In most patients, conduction can move both anterograde (from the atria to the ventricles) and retrograde (from the ventricles to the atria). In a smaller group (approx. 15% of patients), conduction moves in a retrograde manner only. Anterograde conduction by itself is rare. Additionally, the accessory pathway may be left-sided or right-sided. This will affect the changes seen on the ECG (see investigations section). The accessory pathway in Wolff-Parkinson-White Syndrome is sometimes referred to as the ‘ bundle of Kent’. Fig...

WPW syndrome is characterized by a double stimulation of the ventricles. A premature conduction wave via accessory pathways (pre-excitation) stimulates the portions of the ventricles nearest the atrium; then the ventricles depolarize as a result of the conduction wave which proceeds normally through the atrioventricular (AV) node. The clinical significance of this syndrome depends on the appearance of (supraventricular) reentry tachycardias. Remastered ECG from original white on black images via Von Knorre GH.
