Infants born with complete atrioventricular block (CAVB) and fetal bradycardia are frequently born with low birth weight. Three low‐birth‐weight CAVB infants underwent temporary pacemaker implantation, followed by permanent single‐chamber pacemaker implantation at median body weights of 1.7 and 3.2 kg, respectively. All infants caught up with their growth curves and had >3 years of estimated residual battery life. This two‐stage strategy was successful in facilitating permanent pacemaker implantation in low‐birth‐weight babies. Placement of single‐chamber pacemaker on the apex of the left ventricle appears to be associated with longer battery lifespan.
