Unlabelled:
Methadone treatment is a well recognised cause of QT interval lengthening in adults. In this case report, we present for the first time, clinically significant QT interval lengthening in a neonate secondary to maternal methadone treatment. Neonatal paediatricians should be aware of this important and potentially serious clinical phenomenon.
Conclusion:
Bradycardia, tachycardia or an irregular heart rate in an infant born to a mother on methadone treatment should not be ignored and a 12-lead electrocardiogram should be performed. Furthermore, there is also a need for a prospective study of QTc intervals in infants born to mothers receiving methadone.
