An electrocardiogram (ECG) signal contains the electrical activity generated by the contraction of heart muscles. An ECG signal can provide a lot of information about an individual's heart condition and health. That being said, principles of ECG analysis can also be applied to the electrocardiogram of a fetus (FECG) in order to accurately monitor heart development and health during the differen...
BACKGROUND Therapy-refractory supraventricular tachycardia commonly results in hydrops and death in human fetuses. The purpose of this study in fetal sheep was to assess the feasibility of a minimally invasive fetoscopic approach for fetal transesophageal electrocardiography and stimulation aimed at diagnosis and termination of these tachycardias. METHODS AND RESULTS We studied a total of 10 ...
PO-01-207 VERNIX CASEOSA DISTRIBUTION MODULATES NON-INVASIVE FETAL ECG SIGNAL: A COMPUTATIONAL STUDY
Non-invasive fetal ECG (FECG) shows promise as a diagnostic method to monitor health. However, extracting the cardiac signal remains challenge due low signal-to-noise ratio. An important factor is low-conducting layer which forms around fetus from week 28 of gestation called vernix caseosa (VC). We developed an anatomically detailed and biophysically accurate computational model pregnant torso ...
Nowadays, ICA based methods are widely used. However, ICA needs multiples channels for collecting electrocardiogram signals. One of the most significant advantages of utilizing ANFIS networks in FECG extraction is that the methods require only two record signals, one thoracic signal and one abdominal ECG signal. In the present work, ANFIS network is apply to extract the FECG signal from both EC...
Analysis of the fetal heart rate during pregnancy is essential for monitoring proper development fetus. Current techniques lack accuracy in and features acquisition, resulting diagnostic medical issues. The challenge lies extraction ECG from mother pregnancy. This approach has advantage being a reliable non-invasive technique. In present paper, wavelet/multiwavelet method proposed to perfectly ...
Centralized system for fetal home telemonitoring with wireless data transmission based on GSM service and internet is presented in this paper. Cardiotocographic signals are provided by mobile instrumentation which consists of bioelectrical signal recorder and Tablet PC. It enables to support a classical interpretation of cardiotocographic trace by information on fetal electrocardiogram morpholo...
This paper evaluates the performance of some major Independent Component Analysis (ICA) algorithms like Cardoso’s Joint Approximate Diagonalization of Eigen matrices (JADE), Comon’s algorithm and Optimized Generalized Weighted Estimator (OGWE) ICA algorithm in a biomedical blind source separation problem. Independent signals representing Fetal ECG (FECG) and Maternal ECG (MECG) are generated an...
