Abstract: | AV Conduction in WPW. We report an unusual case of a relatively regular wide QRS complex tachycardia alternating with periods of an irregular narrow QRS complex tachycardia during atrial fibrillation in a patient with Wolff-Parkinson-White syndrome. Both tachycardias resulted from atrial fibrillation, the wide QRS complex tachycardia being due to 2:1 AV conduction of a type I atrial fibrillation across a posteroseptal accessory AV connection. |
