The matched filter was used to detect different signal features on an human heart electrocardiogram signal. The waveform features of interest were the QRS Complex, the R-R intervals, and the ST segments of four different electrocardiogram signals. The detection of the QRS Complex and the R-R interval were compared for accuracy and used in determining the length of the heart beat interval which ...

The US Food and Drug Administration recommends submission of digital electrocardiograms in the standard HL7 XML format into the electrocardiogram warehouse to support preapproval review of new drug applications. The Food and Drug Administration scrutinizes electrocardiogram quality by viewing the annotated waveforms and scoring electrocardiogram quality by the warehouse algorithms. Part of the ...

This paper describes a new method for extracting the fetal heart rate (fHR) and the fetal heart rate variability (fHRV) signal non-invasively using abdominal maternal electrocardiogram (mECG) recordings. The extraction is based on the fundamental frequency (Fourier’s) theorem. The fundamental frequency of the mother’s electrocardiogram signal (fo-m) is calculated directly from the abdominal sig...
