This paper discusses a system for unassisted monitoring of (a) adult ECG and (b) in case of pregnant mothers, the mother’s and the fetal ECG (fECG), the latter by its extraction from the overshadowing maternal ECG (mECG). We propose to monitor these vital signals from a bathtub at home with no leads placed on the subject’s body, therefore completely unassisted. The leads are passive, and placed permanently on the inner surface of the bathtub. DSP is used both for extracting the orthogonal vector-cardiogram from the bathtub leads and also for efficient separation of the fECG from the combined mother-and-fetal signal (mfECG) – taking into account a composite, highly complex, medium. Presented also is a novel architecture for on-chip processing based on application-specific CMOS VLSI cells developed in our laboratory.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
