Independent component analysis: fetal signal reconstruction from magnetocardiographic recordings
Independent component analysis (ICA) was used for the processing of cardiological signals obtained by means of fetal magnetocardiography (fMCG), a technique allowing the non-invasive recording of the weak magnetic field variations associated to the electrical activity of the fetal heart. Purpose of the present work was to verify whether a computational-light ICA algorithm (FastICA), tailored to...
متن کاملFetal Magnetocardiographic Source Separation Using the Poles of the Autocorrelation Function
Fetal magnetocardiography (FMCG) have been extensively reported in the literature as a non-invasive, prenatal technique, in which magnetic fields are used to monitor the function of the fetal heart rate. On the other hand, FMCG may be highly noisy, due to the fetal heart dimensions when compared, for example, to the mother’s. In the field of source separation, many works have shown its efficien...
متن کاملMagnetocardiographic rhythm patterns at initiation and termination of fetal supraventricular tachycardia.
BACKGROUND Using fetal magnetocardiography (fMCG), we characterize for the first time the electrophysiological patterns of initiation and termination of reentrant fetal supraventricular tachycardia (SVT), the most common form of life-threatening fetal arrhythmia. METHODS AND RESULTS In contrast to the expectation that reentrant SVT is initiated by spontaneous premature atrial contractions (PA...
متن کاملAnalysis of Pre-processing and Post-processing Methods and Using Data Mining to Diagnose Heart Diseases
Today, a great deal of data is generated in the medical field. Acquiring useful knowledge from this raw data requires data processing and detection of meaningful patterns and this objective can be achieved through data mining. Using data mining to diagnose and prognose heart diseases has become one of the areas of interest for researchers in recent years. In this study, the literature on the ap...
متن کاملa review of mt data processing
magnetotelluric (mt) method is an important passive surface geophysical method which uses the earth’s natural electromagnetic fields to investigate the electrical resistivity structure of the subsurface. the depth of investigation of mt is much higher than that of other electromagnetic (em) methods (vozoff, 1991). for a general conductivity distribution in the earth, the horizontal electric fie...
