Prolongation of the QT Interval and the Sudden Infant Death Syndrome

Abstract
The unexpected and unexplained death of an infant is a tragic occurrence. When the infant is less than one year of age and the cause remains unknown despite a thorough investigation including a complete autopsy, examination of the death scene, and review of the clinical and family history, the term “sudden infant death syndrome” (SIDS) is applied.1,2 This disorder has an incidence of 1.6 per 1000 live births in the United States, 0.7 per 1000 live births in Italy, and 2.5 per 1000 live births in the United Kingdom, making it the most common cause of death among children . . .
