Prenatal presentation of fetal bradycardia and long <scp>QT</scp> syndrome
The most common finding in fetuses with persistent sinus bradycardia without major congenital heart disease or autoimmune disease is LQTS. Prenatal genetic testing enables tailored parental counseling and management of the pregnancy. Although N-LVIRT and LVIRT were not above the threshold values in most cases, they remain important measures for investigation in future studies. © 2026 International Society of Ultrasound in Obstetrics and Gynecology.
