A New Algorithm for Fetal QRS Detection in Abdominal Recordings
نویسندگان
چکیده
The acquisition and the analysis of electrophysiological signals are often followed by the detection of parameters of clinical importance. In the case of fetal electrocardiogram signal, the presence of QRS complex is the best indicator of the fetal heart rate, as it is directly correlated with the fetal cardiac activity. However, to detect this complex, it is necessary to separate the signal from the maternal ECG signal. In this paper, a new algorithm for the fetal QRS detection is presented. This algorithm is based on two methods: the blind source separation method and the empirical mode decomposition (EMD) method. The results obtained by the application of this algorithm to recordings of fetal electrocardiogram signals from the DaISy database show its good performance.

Background: Fetal electrocardiography is a developing field that provides valuable information on the fetal health during pregnancy. By early diagnosis and treatment of fetal heart problems, more survival chance is given to the infant.Objective: Here, we extract fetal ECG from maternal abdominal recordings and detect R-peaks in order to recognize fetal heart rate. On the next step, we find a be...

Fetal heart rate estimated from fetal electrocardiogram (fECG), recorded via electrodes placed on the maternal abdomen, represents an important tool in evaluating fetal distress and diagnosing fetal diseases. However, due to poor signal to noise ratio (SNR) of the fECG, the abdominal fECG analysis is still very difficult, despite of significant advances in technology and in the field of electro...

The QRS detection is key component of each automated ECG analysis. For this purpose a lot of QRS algorithms have been already developed. In the same time the number of new published methods continues to grow up. This implicitly proves the impossibility of building such detector that could totally cover the variety of all shapes of ventricular beats encountered in practice. Generally, limited st...
