Abstract
A QRS filter is an integral part of most heart-rate monitors and arrhythmia analysis systems. A filter design was optimized with Wiener's minimum mean-squared error criterion or a maximum snr criterion of a matched filter. The maximum snr is the criterion of choice for a QRS detector. information about the signal shape and the precise knowledge of the noise spectrum is not generally available. Signal and noise power was calculated from the knowledge of their power spectra and coherence function. With limited data it is shown that a bandpass filter with center frequency of 18 Hz and a high Q is optimal.
