The syndrome of the shortened P-R interval associated with widened QRS as an anomaly of the conduction system of the heart has long been recognized in the adult.
Since few cases of Wolff-Parkinson-White syndrome have been reported in children in association with congenital heart disease, a case report is presented in a boy whose first episode of paroxysmal tachycardia occurred at seven months of age.
The diagnosis of congenital heart disease seems likely in view of the finding of a pronounced, widely heard systolic murmur first noted at the age of 2
years, and never associated with rheumatism or other signs of infection.
A history of paroxysmal tachycardia in infants and children warrants cardiographic investigation between attacks.
