Multiresolution wavelet analysis applied to heartbeat intervals
has been shown to be a potential clinical tool to discriminate
healthy patients from those with a cardiac pathology [1].
In our work we discuss an alternative way of analysis by deliberately
removing the heart rate variability and by studying measures for the
similarity of electrocardiogramm (ECG) segments (R-R intervals).
We furthermore investigate the robustness of the results with respect
to wake and sleep periods.
