Ballistocardiography and Seismocardiography: A Review of Recent Advances
(2015-07-01)
Article
Accés obertIn the past decade, there has been a resurgence in the field of unobtrusive cardiomechanical assessment, through advancing methods for measuring and interpreting ballistocardiogram (BCG) and seismocardiogram (SCG) signals. ... -
Characterization of cardiac and respiratory system of healthy subjects in supine and sitting position
(Springer, 2019-09)
Capítol de llibre
Accés restringit per política de l'editorialStudies based on the cardiac and respiratory system have allowed a better knowledge of their behavior to contribute with the diagnosis and treatment of diseases associated with them. The main goal of this project was to ... -
Correntropy-based Analysis of Respiratory Patterns with Chronic Heart Failure
(2009)
Text en actes de congrés
Accés obertA correntropy-based technique is proposed for the analysis and characterization of respiratory flow signals in chronic heart failure (CHF) patients with both periodic and nonperiodic breathing (PB and nPB), and healthy ... -
Diagnosis of ischemic heart disease with cardiogoniometry – Linear discriminant analysis versus support vector machines
(2008)
Text en actes de congrés
Accés restringit per política de l'editorialThe Ischemic Heart Disease (IHD) is characterized by an insufficient supply with blood of the myocardium usually caused by an artherosclerotic disease of the coronary arteries (coronary artery disease CAD). The IHD and its ... -
Disseny i implementació d'un sistema de monitorització no invasiva de paràmetres cardiovasculars per a pilots d'aeronau
(Universitat Politècnica de Catalunya, 2014-07-04)
Treball Final de Grau
Accés restringit per decisió de l'autorThis work explains the implementation of a non-invasive system for cardiovascular monitoring based on the head-BCG's measurement. The ballistocardiogram (BCG) is a mechanical signal of cardiovascular origin, in which there ... -
Electrophysiological effects of selective atrial coronary artery occlusion in humans
(2016-06-07)
Article
Accés obertBackground-The arrhythmogenesis of ventricular myocardial ischemia has been extensively studied, but models of atrial ischemia in humans are lacking. This study aimed at describing the electrophysiological alterations ... -
Heart rate complexity analysis in Brugada syndrome during physical stress testing
(Institute of Physics (IOP), 2017-02-01)
Article
Accés obertSymptoms such as ventricular arrhythmias in Brugada syndrome (BS) typically occur at rest, especially during sleep, suggesting that the autonomic nervous system (ANS) function may be relevant in the arrhythmogenesis of the ... -
Low level and high frequency fragmentation of the QRS changes during acute myocardial ischemia in patients with and without prior myocardial infarction
(Computing in Cardiology, 2014)
Comunicació de congrés
Accés obertHigh frequency (HF) QRS fragmentation and very-low amplitude abnormal intra-QRS potential (uAIQP) analyses have been used to track ischemic changes during coronary artery occlusions. The aim of this study was to assess the ... -
