[Familial epilepsy seizure disclosing long QT syndrome].

The Romano-Ward syndrome shows a congenital prolonged QT on the electrocardiogram. It is often revealed by syncopes, sudden death and, in rare cases, by an epileptic attack. We report the cases of two sisters presenting this syndrome. One of them presented an inaugural epileptic attack. The electrocardiogram returned to normal and the seizures disappeared after a treatment with beta-bloquants.
