Based on a brief introduction to fetal electrocardiogram (FECG), this paper illustrates the clinical application of FECG technology in recent years in aspects such as detecting fetal arrhythmias and monitoring fetal intrauterine hypoxia in patients with pregnancy-induced hypertension syndrome. It sorts out the limitations of FECG itself. This paper also summarizes the progress of FECG signal processing techniques, and looks forward to the development prospect of FECG in the future.
