Cardiac involvement (Wolff-Parkinson-White syndrome) in tuberous sclerosis.

A surface electrocardiogram showing type B Wolff-Parkinson-White syndrome pattern was part of the cardiac findings in a female of 24 with florid features of tuberous sclerosis. She had cardiomegaly but no intracardiac tumour was demonstrated. Wolff-Parkinson-White syndrome, though rare, has previously been described in association with tuberous sclerosis in children but not before in adults.
