A digital filtering algorithm is presented that is suitable for automatic detection of QRS complexes. A bandpass nonrecursive finite impulse response ( NRFIR ) filter is used to suppress lower frequency frequencies of the ECG signal, which are inherently nonstationary, and to model the frequency response of the optimal matched filter. This digital filter is time saving and it provides linear phase characteristics so that the time of QRS occurrences is not affected. Its capability is demonstrated by applying the filtering to simulated and true ECG records. The detection rate very noisy records reaches 100 percent.
