Title
(EN) METHOD AND SYSTEM FOR ENGINEERING CYCLE VARIABILITY-RELATED FEATURES FROM BIOPHYSICAL SIGNALS FOR USE IN CHARACTERIZING PHYSIOLOGICAL SYSTEMS
(FR) PROCÉDÉ ET SYSTÈME DE MODIFICATION DE CARACTÉRISTIQUES ASSOCIÉES À LA VARIABILITÉ DE CYCLE À PARTIR DE SIGNAUX BIOPHYSIQUES DESTINÉS À ÊTRE UTILISÉS DANS LA CARACTÉRISATION DE SYSTÈMES PHYSIOLOGIQUES
Abstract
(EN) The exemplified methods and systems facilitate the use, for diagnostics, monitoring, or treatment, of one or more cycle variability based features or parameters determined from biophysical signals such as cardiac or photoplethysmography signals that are acquired non-invasively from surface sensors placed on a patient while the patient is at rest. The estimated metric may be used to assist a physician or other healthcare provider in diagnosing the presence or non-presence and/or severity and/or localization of diseases or conditions or in the treatment of said diseases or conditions.
(FR) Les procédés et systèmes illustrés facilitent l'utilisation, pour le diagnostic, la surveillance ou le traitement, d'une ou de plusieurs caractéristiques ou paramètres basés sur la variabilité de cycle déterminés à partir de signaux biophysiques tels que des signaux cardiaques ou de photopléthysmographie qui sont acquis de manière non invasive à partir de capteurs de surface placés sur un patient tandis que le patient est au repos. La métrique estimée peut être utilisée pour aider un médecin ou un autre fournisseur de soins de santé à diagnostiquer la présence ou la non-présence et/ou la gravité et/ou la localisation de maladies ou d'états ou dans le traitement desdites maladies ou desdits états.
