Filters yield concordant late potentials; leaves open QRS duration effects on SAECG diagnostic thresholds.
Does the Fourier transform non-recursive digital filter yield comparable late potential parameters to the bidirectional digital recursive filter in signal averaged ECGs?
Fourier transform and bidirectional digital filters provide highly correlated and diagnostically concordant late potential parameters, though Fourier filtering results in a longer QRS duration.
Abboud et al. (1991) studied this question.
