title: Hereditary atrioventricular conduction defect in a child.
abstract: Hereditary atrioventricular conduction defect is an uncommon cause of acquired complete heart block in children. We report a father and son, both of whom presented with seizures as the initial manifestation of acquired complete heart block and required permanent pacemaker implantation. A review of the variations of this entity and the histopathological findings of previously reported cases is presented. Family members of patients with acquired heart block of uncertain etiology should be examined for the presence of conduction abnormalities that may progress to complete heart block.
