Successful 2-Stage Pacemaker Implantation for Atrioventricular Block in a Low-Birth-Weight Infant with Congenital Heart Disease: Case Report.

Congenital heart block is a potentially life-threatening condition with high morbidity and mortality, especially in the presence of congenital heart disease. We present the case of a low-body-weight premature infant with complex single ventricle congenital heart disease and high-grade atrioventricular block. A 2-staged pacing approach provided atrio-ventricular synchrony and allowed her to grow until a permanent dual-chamber pacemaker system could be implanted.
