Overview on noninvasive fetal ECG extraction algorithms / 医疗卫生装备

The main characteristics were introduced for the fetal electrocardiogram by noninvasive collection. The basic principles and the research status were summarized of five algorithms and their related improvement algorithms for noninvasive fetal ECG signal extraction.The mode of electrodes,advantages and disadvantages were analyzed for kinds of algorithms.It's pointed out that multiple births should be taken into account for fetal ECG signals extraction in the future.The portable fetal cardiac monitoring device should be studied in case the real-time and accuracy of algorithms can be improved, making the baby's electrical monitoring to be personalized and family-friendly.
