Wavelet analysis of blood pressure waves in vasovagal syncope

open access: yes, 1999
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 ...

Transfer Information Assessment in Diagnosis of Vasovagal Syncope Using Transfer Entropy

open access: yesEntropy, 2019
The paper presents an application of Transfer Entropy (TE) to the analysis of information transfer between biosignals (heart rate expressed as R-R intervals (RRI), blood pressure (sBP, dBP) and stroke volume (SV)) measured during head up tilt testing ...

Cardiovascular Autonomic Dysfunction Is the Most Common Cause of Syncope in Paced Patients

open access: yesFrontiers in Cardiovascular Medicine, 2019
Introduction: Syncope and orthostatic intolerance in paced patients constitute a common clinical dilemma. We, thus, aimed to determine the etiology of syncope and/or symptoms of orthostatic intolerance in paced patients.Methods: Among 1,705 patients with
