title: Optimization of bi-directional digital filtering for drift suppression in electrocardiogram signals.
abstract: Baseline drift may often impede automatic ECG measurement and interpretation. Known methods for drift suppression do not take into consideration specific waveform parameters of various ECG signals. We propose high-pass filtering with adaptable cut-off frequency in order to keep RS amplitude changes below a selectable threshold and to preserve ST segment shape within acceptable limits.
