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.
患有完全性房室传导阻滞（CAVB）且有胎儿心动过缓的婴儿出生时常常体重过低。三名低体重CAVB婴儿接受了临时起搏器植入，随后分别在平均体重为1.7千克和3.2千克时接受了永久性单腔起搏器植入。所有婴儿均赶上了他们的生长曲线，并且估计剩余电池寿命超过3年。这种两阶段策略成功地促进了低体重婴儿的永久性起搏器植入。将单腔起搏器置于左心室心尖似乎与更长的电池寿命相关。
