Spatiotemporal QRST cancellation techniques for improved characterization of atrial fibrillation in the surface ECG
A new two-step approach to QRST complex cancellation in ECGs with atrial fibrillation is presented in which spatiotemporal properties of the ECG are considered. The method was found to produce QRS related residuals with a substantially lower amplitude and thereby the resulting residual ECG should be better suited for spectral analysis.
