Wavelet Analysis of Blood Pressure Waves in Vasovagal Syncope

We describe the multiresolution wavelet analysis of blood pressure waves in vasovagal-syncope affected patients compared with healthy people. We argue that there exist discriminating criteria which allow us to isolate particular features, common to syncope-affected patients sample, indicating a tentative, alternative diagnosis methodology for this syndrome. We perform a throughout analysis both in the Haar basis and in a Gaussian one, with an attempt to grasp the underlying dynamics.
