We encountered a case of fetal bradycardia (57 bpm) induced by heart block. The continuous intravenous administration of ritodrine to a mother to treat fetal brady-cardia at 28 weeks of gestation successfully increased the fetal ventricular rate by 15 bpm (from 57 to 72 bpm). Pregnancy was continued for 10 weeks, and fetal cardiac failure did not occur. The fetal ventricular rate gradually decreased to 52 bpm after discontinuation of the ritodrine infusion. It is suggested that maternal administration of ritodrine can be considered in a case of life-threatening fetal bradycardia induced by complete heart block.
我们遇到了一例由心脏传导阻滞引起的胎儿心动过缓（57次/分钟）。在妊娠28周时，为治疗胎儿心动过缓，对母亲持续静脉输注利托君，成功使胎儿心室率提高了15次/分钟（从57次/分钟升至72次/分钟）。妊娠持续了10周，未发生胎儿心力衰竭。停止输注利托君后，胎儿心室率逐渐降至52次/分钟。对于由完全性心脏传导阻滞引起的危及生命的胎儿心动过缓病例，建议考虑对母亲使用利托君。
