To determine whether the fetal heart behaves differently in normotensive and hypertensive pregnancies, the changes in baseline fetal heart rate were investigated prospectively from 15 to 38 weeks gestation in 16 women who were normotensive at the time of booking in the antenatal clinic. Fetal heart rate recordings were made ultrasonically, and were computer-processed by the programs TELEPLOT and BASELINE. Those women who remained normotensive exhibited a decrease of fetal heart rate with advancing gestational age, but this did not occur in the six women who eventually developed hypertension.
为了确定胎儿心脏在血压正常和高血压妊娠中的表现是否不同，对16名在产前诊所登记时血压正常的孕妇在妊娠15至38周期间的基线胎儿心率变化进行了前瞻性研究。胎儿心率记录通过超声进行，并由TELEPLOT和BASELINE程序进行计算机处理。那些血压一直正常的女性，其胎儿心率随着孕周增加而下降，但最终患高血压的6名女性并未出现这种情况。
