Abstract
We have previously shown that nonlinear measures of regularity and complexity are very useful as complimentary measures to the linear measures of time and frequency domain of beat-to-beat heart rate and QT intervals. In this study, we have applied Cross-ApEn, a nonlinear measure that can give an index of dissociation between two time series. We have shown that it can be superior to the linear measure of cross-coherence between the two signals. The practical implications of this finding have been further discussed in detail.
