Electrocardiogram Waveform Feature Extraction Using the Matched Filter
نویسنده
چکیده
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 is necessary to determine the heart rate variability. The detection of the ST segment, which is a precursor of possible cardiac problems, was more difficult to extract using the matched filter due to noise and amplitude variability.
