Interest in clinical fetal electrocardiography dates back to 1906 when Cremer4 published two tracings apparently showing fetal deflections of about 0.5 mm. amplitude superimposed on the maternal electrocardiogram of a nine-months gravid woman. The records were obtained with a string galvanometer electrocardiograph with one lead on the abdomen and one in the vagina. During the next 25 years Foa7...

An automated method to assess the fetal physiological development is introduced which uses the component intervals between fetal cardiac valve timings and the Q-wave of fetal electrocardiogram (fECG). These intervals were estimated automatically from one-dimensional Doppler Ultrasound and noninvasive fECG. We hypothesize that the fetal growth can be estimated by the cardiac valve intervals. Thi...

UNLABELLED Couplings between uterine contractions (UC) and fetal heart rate (fHR) provide important information on fetal condition during labor. At present, couplings between UC and fHR are assessed by visual analysis and interpretation of cardiotocography. The application of computerized approaches is restricted due to the non-stationarity of the signal, missing data and noise, typical for fHR...

Cardiac abnormalities are one of the main problems present in newborns. They can cause fetal death. If they are detected in time, it is possible to cure or to take all necessary precautions during childbirth. Our work proposes a method for detecting cardiac arrhythmias in the fetus by using digital filters and discrete wavelet transforms. On the basis of signals from the database DaIS, our meth...

Non-invasive fetal electrocardiograms (FECGs) are an alternative method to standard means of fetal monitoring which permit long-term continual monitoring. However, in abdominal recording, the FECG amplitude is weak in the temporal domain and overlaps with the maternal electrocardiogram (MECG) in the spectral domain. Research in the area of non-invasive separations of FECG from abdominal electro...

BACKGROUND Indirect fetal electrocardiography is preferable to direct fetal electrocardiography because of being noninvasive and is applicable also during the end of pregnancy, besides labor. Still, the former is strongly affected by noise so that even R-peak detection (which is essential for fetal heart-rate evaluations and subsequent processing procedures) is challenging. Some fetal studies h...

BACKGROUND The fundamental assumptions for various kinds of fetal electrocardiogram (fECG) extraction methods are not consistent with each other, which is a very important problem needed to be ascertained. METHODS Based on two public databases, the regularity on ECG wave durations for normal sinus rhythm is investigated statistically. Taking the ascertained regularity as an assumption, a new ...

The fetal electrocardiogram (FECG) has been recorded from 155 women in labor using a fetal scalp electrode and a minicomputerized enhanced averaging technique. Fetal hypoxia, acidosis, and stress have been diagnosed by analysis of blood from the fetal scalp, and post delivery from full gas analysis from blood taken from the umbilical artery and vein. Umbilical venous levels of serum lactate, ad...

Objective This study aims to report our experience using the Monica AN24 (Monica Healthcare Ltd., Nottingham, United Kingdom), a maternal transabdominal fetal electrocardiographic monitor, in a case series of fetuses with arrhythmias. Study Design We recorded fetal electrocardiograms (fECGs) on subjects with fetal arrhythmias diagnosed by fetal echocardiogram. Fetal heart rate and rhythm were d...
