Prenatal findings in patients with prolonged QT interval in the neonatal period.

Abstract

Sinus bradycardia in an otherwise normal fetus may be a symptom of long QT syndrome. Postnatal ECGs and a family examination are strongly recommended in these children. In fetuses with frequent runs of ventricular tachycardia and intermittent second degree atrioventricular block long QT syndrome should be suspected prenatally. These high risk patients should be delivered in centres with a paediatric cardiology unit.
