Haddad Syndrome

Abstract

Congenital central hypoventilation syndrome (CCHS) causes predominantly sleep apnoea and is one of a growing number of inherited disorders characterised by autonomic nervous system dysfunction/dysregulation (ANSD). In association with Hirschsprung's disease (HSCR), it presents as Haddad's syndrome. We report a case of Haddad's syndrome complicated by sinus node dysfunction.
