Atrioventricular junctional and orthodromic atrioventricular reentrant tachycardia in Wolff-Parkinson-White syndrome.
The existence of two or more types of reentrant tachycardias in the same patient with Wolff-Parkinson-White syndrome has been emphasized, and the occurrence of orthodromic atrioventricular (AV) reentrant tachycardia and AV junctional reentrant tachycardia have been well documented. This report describes a patient with Wolff-Parkinson-White syndrome in whom the phenomena of spontaneous transition from AV reentry to AV junctional reentry and adenosine-induced conversion from AV junctional reentry to AV reentry were observed.
