Pacemaker Management and In-Hospital Outcomes in Neonatal Congenital Atrioventricular Block
Authors' conclusion
Over 18.5 years, in-hospital mortality occurred in 36.2% of nCAVB patients with CHD and 8.4% with non-CHD. Associations with increased in-hospital mortality included CHD and prematurity and decreased with pacemaker placement.
