Jervell and Lange-Nielsen QT syndrome: a case report from Saudi Arabia.

A family with two of its members having Jervell and Lange-Nielsen syndrome is reported for the first time from Saudi Arabia. A history of syncopal attack in a child with hearing loss and the sudden death of her brother while playing suggested the possibility of the syndrome. Electrocardiogram and full ENT and audiological assessment revealed Jervell and Lange-Nielsen syndrome in the living child. Treatment was given and the condition is now under control.
