超声多普勒胎儿信号用于心电成像时，虽然信号本身很容易获得，信噪比很好，但由于信号处理难以获得一致的触发点，因此胎儿心率记录的可靠性有限。然而，利用自动适应算法的相关技术开发了一种独特的信号处理系统，解决了旧多普勒心电仪所存在的几乎所有困难，并表明超声多普勒胎儿信号也可以提供与胎儿心电图系统相容的心率记录。在即将到来的面向微处理器的仪器时代，该方法是一种最有前途的方法。
For use in a cardiotocograph, ultrasound Doppler fetal signals provide merely a limited reliability of the fetal heart rate record because of the difficulty of signal processing to obtain a consistent trigger, although the signal itself is easy to obtain with an excellent signal-to-noise ratio. However, a unique signal processing system was developed using a correlation technique with an automatic adaptation algorithm, which solved almost all of the difficulties associated with the old Doppler cardiotocograph and showed that the ultrasound Doppler fetal signal can also provide heart rate records compatible to that obtained by a fetal ECG system. The method is a most promising one in the coming age of microprocessor-oriented instrumentation.
