Congenital heart block is a rare condition that affects the heart's electrical system, which controls and coordinates its pumping function. It means the heart developed with some kind of flaw or weakness. Congenital heart disease accounts for nearly one third of all major congenital anomalies and is the most common congenital condition diagnosed in newborns. These are cardiac anomalies arising as a result of a defect in the structure or function of the heart and great vessels which is present at birth.

With an incidence that varies between 0.8 to 2% in neonates, congenital heart disease contributes to a much larger fraction of stillbirths.
