Title: Blood pressure regulation failure prediction using the PPG

Abstract: Syncope is a transient and self-limiting loss of consciousness caused by the failure of the blood pressure regulation mechanisms. Although its main causes are generally benign, it has a great impact in elderly populations, where morbidity is particularly high. In these populations, syncopes are commonly associated with high rates of falls and hospitalisations, and consequently with reduced physical and social activity, mental decline and incidence of medical conditions.  In this talk I will present a non-invasive solution for prediction of neurally mediated syncope based on the analysis of the electrocardiogram (ECG) and photoplethysmogram (PPG) alone. It  will focus on three main topics: 1) The detection motion artifacts in PPG signals based analysis of the variations in the time and the period domain characteristics of the PPG signal; 2) The extraction of cardiovascular performance surrogates based on the decomposition and analysis of PPG pulses and; 3) The prediction of episodes of blood pressure regulation failure based on the analysis of both ECG and PPG, and on the analysis PPG alone.

Short bio: Dr. Ricardo Couceiro received his MSc in Biomedical Engineering from the University of Coimbra in 2008 and PhD degree on Information Science and Technology from the University of Coimbra in 2015. He has been a research member of CISUC (Center for Informatics and Systems of University of Coimbra) since 2006. He participated in several national and international projects since 2006 (e.g. MyHeart, Heartcycle and Welcome) and he is the project manager of the H2020 project LINK. His research interests include biomedical signal processing, pattern recognition and modelling applied to the analysis of the cardiovascular system. His publications include several book chapters and over 40 papers in refereed national and international journals and conferences.
