The development of atrial fibrillation exposed previously undocumented anterograde accessory pathway conduction, unmasking Wolff-Parkinson-White syndrome in three patients.
Atrial fibrillation can unmask anterograde accessory pathway conduction in patients with previously latent Wolff-Parkinson-White syndrome.
AF may unmask latent WPW; case reports leave open systematic evaluation in new-onset AF.
In three patients anterograde conduction across a previously undocumented accessory pathway was exposed by the development of atrial fibrillation. This unusual presentation illustrates the possible unmasking of the Wolff-Parkinson-White syndrome by other factors in patients who have not previously demonstrated the potential for anterograde accessory pathway conduction.
