Nonlinear Local Projection Technique for ECG
The electrical activity of the heart shows complex dynamical behavior. This paper presents a nonlinear local projective noise reduction filter for electrocardiograms. In order to automatically detect the best neighborhood size of the projection, recurrence plots are used. The minimum gives a clear indication of the best size of the neighborhood in the embedding space. We also use the box-assisted algorithm to efficiently find nearest neighbors in m-dimensional space. The method is successfully applied to ECG signals.
