Multiscale analysis of blood pressure signals

TL;DR

This paper compares wavelet-based multiscale analysis methods for blood pressure signals in patients with vasovagal syncope and healthy individuals, showing both approaches effectively distinguish between the groups.

Contribution

It demonstrates the equivalence of scale-dependent and scale-independent wavelet measures in discriminating vasovagal syncope from healthy blood pressure signals.

Findings

Both methods achieve significant separation between patient groups.

Wavelet analysis provides a multiscale perspective on blood pressure signals.

Haar and Gaussian wavelets yield comparable results.

Abstract

We describe the multiresolution wavelet analysis of blood pressure waves in vasovagal syncope-affected patients compared with those in healthy people, using Haar and Gaussian bases. A comparison between scale-dependent and scale-independent measures discriminating the two classes of subjects is made. What emerges is a sort of equivalence between these two methodological approaches, that is, both methods reach the same statistical significance of separation between the two classes.
