Wolff-Parkinson-White syndrome in pregnancy.

Supraventricular tachyarrhythmia in association with Wolff-Parkinson-White syndrome is reported in 3 pregnant women. The management of such arrhythmia is discussed, and it is suggested that pregnancy may predispose asymptomatic patients with Wolff-Parkinson-White syndrome toward exhibiting arrhythmia. The diagnosis and etiologic considerations of this syndrome in association with pregnancy are reviewed, and it is concluded that further investigations are needed to determine the incidence of Wolff-Parkinson-White syndrome-induced arrhythmia in pregnancy.
