A 21 week fetus was diagnosed with complete heart block. From the first diagnosis until 38 weeks gestation, umbilical venous pulsations occurred during ventricular systole. The ventricular frequency was 49 bpm. The venous pulsations corresponded with the ventricular frequency. At 38 weeks venous pulsations also occurred during ventricular diastole. Umbilical pulsations during diastole were associated with a decrease of ventricular frequency to 28 bpm and fetal hydrops. The venous pulsations during ventricular systole seem to be characteristic of complete heart block. The pulsations during ventricular diastole reflect the fetal heart failure. Doppler ultrasound aids in the diagnosis and surveillance of the fetus with complete heart block.
一名21周的胎儿被诊断为完全性心脏传导阻滞。从首次诊断到妊娠38周，心室收缩期出现脐静脉搏动。心室频率为49次/分钟。静脉搏动与心室频率一致。38周时，心室舒张期也出现静脉搏动。舒张期的脐搏动与心室频率降至28次/分钟及胎儿水肿有关。心室收缩期的静脉搏动似乎是完全性心脏传导阻滞的特征。心室舒张期的搏动反映胎儿心力衰竭。多普勒超声有助于诊断和监测患有完全性心脏传导阻滞的胎儿。
