Wolff-Parkinson-White Syndrome
This paper reports a patient with Wolff-Parkinson-White syndrome who presented with a tachycardia showing an unusual QRS morphology closely resembling that of a ventricular tachycardia. On reversal to a normal rhythm the electrocardiogram showed changes of a type A preexcitation, with subsequent conversion to a type B pattern. This phenomenon was observed on two separate occasions. Such convers...

Wolff-Parkinson-White (WPW) syndrome is a cardiac conduction disorder that presents with potentially life-threatening consequences. Wolff-Parkinson-White syndrome-induced dysrhythmias account for 20% of all supraventricular tachycardias that occur in the general population. Clinical presentations range from no symptoms to a sudden cardiac arrest. The risk of sudden death is always present with ...

WPW syndrome is a rare congenital heart disease due to an accessory pathway between the atrium and the ventricle. Its ECG pattern is characterized by a short PR interval, a delta wave, a wide QRS complex and an abnormal ventricular repolarisation. Patients are usually asymptomatic, or have frequent paroxysmal episodes of tachycardia. These tachycardias are supraventricular tachycardias related ...

Concealed conduction into accessory atrioventricular pathways has been postulated to explain variability of R-R intervals during atrial fibrillation in patients with Wolff-Parkinson-White syndrome. We examined the occurrence of concealed conduction into atrioventricular pathways using extrastimulus techniques in 26 consecutive patients undergoing electrophysiologic studies for the Wolff-Parkins...
