Extraction of Fetal QRS Complex from Abdominal ECG Signals

چکیده
Background: Extraction of Fetal ECG signal from non-invasive abdominal ECG signal is an important clinical application. Fetal ECG signal provides significant and valuable information about the fetal heart growth and health condition. Objective: Abdominal signals are usually corrupted by high amplitude maternal ECG signals and often found superimposed with the Fetal ECG signal. Suppression of maternal peaks for proper Fetal ECG signal extraction is attempted in our work. Method: A multichannel Fetal ECG signal extraction procedure is proposed in this work using Multivariate Empirical Mode Decomposition (MEMD) and Singular Value Decomposition (SVD). Observation: Patient dataset from three pregnant women is used for evaluating our procedure. The proposed method produced an average detection accuracy of fetal heart rate of 85.33% (min: 75 and max: 100).

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...
متن کاملA New Algorithm for Fetal QRS Detection in Abdominal Recordings
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 fr...

In this paper, we propose a technique of artificial intelligence called adaptive neuro fuzzy inference system (ANFIS) for canceling maternal electrocardiogram (MECG) in fetal electrocardiogram extraction (FECG).This technique is used to estimate the MECG present in the abdominal signal of a pregnant woman. The FECG is then extracted by subtracting the estimated MECG from the abdominal signal. P...
متن کاملA non-invasive methodology for fetal monitoring during pregnancy.
OBJECTIVES This paper describes a methodology for the monitoring of the fetal cardiac health status during pregnancy, through the effective and non-invasive monitoring of the abdominal ECG signals (abdECG) of the mother. METHODS For this purpose, a three-stage methodology has been developed. In the first stage, the fetal heart rate (fHR) is extracted from the abdECG signals, using nonlinear a...
متن کاملState - Space Averaging for Maternal Ecg Suppression
In this paper a new method of maternal electrocardiogram suppression for fetal component extraction from one-channel maternal abdominal bioelectric signals is proposed. The method performs maternal ECG estimation by application of state-space averaging. The estimated signal is subtracted from the original one and this way suppressed. The method parameters allow us to balance between the precisi...
