A syndrome characterized by history of syncopal episodes and a long QT interval, sometimes leading to sudden death (DEATH, SUDDEN, CARDIAC) due to paroxysmal ventricular arrhythmia. A form associated with autosomal recessive inheritance and congenital deafness is called the JERVELL-LANGE NIELSEN SYNDROME. An autosomal dominant form without deafness is called the ROMANO-WARD SYNDROME.
