    Master thesis (pre-Bologna period)
    Open Access
  • 4D Cardiac Segmentation and Respiratory Motion Modeling of the Human Heart 

    Crosas Cano, Guillem (Universitat Politècnica de Catalunya, 2009-06)
    Master thesis (pre-Bologna period)
    Open Access
    Atrial Fibrillation (AF) is a growing problem in modern societies with an enormous impact in both short term quality of life and long term survival. A recently developed promising approach to cure AF uses radiofrequency ...
  • A 1D lumped-parameter/3D CFD approach for pressure drop in the aortic coarctation 

    Soudah Prieto, Eduardo; Bordoné, Maurizio; Dadvand, Pooyan; Rossi, Riccardo (Springer, 2012)
    Conference report
    Restricted access - publisher's policy
    Aortic Coarctation is a congenital constriction of the aorta that increases blood pressure above the constriction and hinders the flow below it. Based on a 3D surface mesh of a moderate thoracic coarctation, a high quality ...
  • ''Análisis de señales electrocadiográficas en pacientes con síndrome de Brugada en riesgo de arritmias malignas'' 

    Berná Rufete, Nerea (Universitat Politècnica de Catalunya, 2018-10-23)
    Bachelor thesis
    Restricted access - author's decision
    El síndrome de Brugada és una malaltia del cor d'origen genètic que pot ser causant d'arrítmies ventriculars i morts sobtades sense cardiopatia estructural evident. En la majoria dels casos, aquests esdeveniments succeeixen ...
  • Boosting the chances to improve stroke treatment 

    Cobo Valeri, Erik; Secades, Julio; Miras, Francesc; González, José Antonio; Saver, Jeffrey L.; Corchero García, Cristina; Rius Carrasco, Roser; Dávalos, Antoni (2010-03)
    Article
    Open Access
    Background and Purpose—There is a lack of agreement regarding measuring the effects of stroke treatment in clinical trials, which often relies on the dichotomized value of 1 outcome scale. Alternative analyses consist ...
  • Building a Parameterized 4D Cardiac Model with Respiratory Motion from 2D MR Time Series 

    Queralt Madrigal, Marc (Universitat Politècnica de Catalunya, 2010-06)
    Master thesis (pre-Bologna period)
    Open Access
    Covenantee:  Northeastern University
    Atrial fibrillation (AF) is a growing problem in modern societies with an enormous impact in both short term quality of life and long term survival. A recently developed promising approach to cure AF uses radiofrequency ...
  • Comparison of Low-order 4D Dynamical Models for Cardiac Respiratory Motion using MRI 

    Coll Font, Jaume (Universitat Politècnica de Catalunya / Northeastern University, 2011-12-18)
    Master thesis (pre-Bologna period)
    Open Access
    Covenantee:  Northeastern University
    English: cardiovascular diseases account for more than one third of the annual mortal rate in western countries. Although AF does not directly lead to mortality is pointed as one of the possible causes of stroke. Recent ...
  • Computing and visualizing informative trajectories in temporaly annotated data 

    Zamora Casals, Martí (Universitat Politècnica de Catalunya, 2017-07-04)
    Master thesis
    Open Access
    A trajectory in the medical world, is the sequence of events that occur during the life of a patient. In the recent years, these trajectories have been stored in the Electronical Health Records and many of the health ...
  • Dimensionality reduction oriented toward the feature visualization for ischemia detection 

    Delgado-Tejos, Edilson; Perera Lluna, Alexandre; Vallverdú Ferrer, Montserrat; Caminal Magrans, Pere; Castellanos Dominguez, German (2009-03-16)
    Article
    Open Access
    An effective data representation methodology on high-dimension feature spaces is presented, which allows a better interpretation of subjacent physiological phenomena (namely, cardiac behavior related to cardiovascular ...
  • Multifractal characterization of the autonomous nervous system during prolonged coronary artery occlusion 

    Magrans Nicieza, Rudys; Gomis Román, Pedro; Caminal Magrans, Pere; Wagner, Galen (2009)
    Conference lecture
    Open Access
    We assess the autonomic nervous system response during prolonged percutaneous transluminal coronary angioplasty (PTCA) by heart rate variability analysis using multifractal indices. These indices are also used to evaluate ...
  • Multivariate classification of Brugada syndrome patients based on autonomic response to exercise testing 

    Calvo, Mireia; Romero, Daniel; Le Rolle, Virginie; Béhar, Nathalie; Gomis Román, Pedro; Mabo, Philippe; Hernández, Alfredo I. (Public Library of Science (PLOS), 2018-05-15)
    Article
    Open Access
    Ventricular arrhythmias in Brugada syndrome (BS) typically occur at rest and especially during sleep, suggesting that changes in the autonomic modulation may play an important role in arrhythmogenesis. The autonomic response ...
  • Non-linear dynamic analysis of RR signals in patients with and without excessive daytime sleepiness 

    Melia, Umberto Sergio Pio; Guaita, Marc; Vallverdú Ferrer, Montserrat; Caminal Magrans, Pere; Clarià Sancho, Francesc; Embid, Cristina; Vilaseca, Isabel; Salamero, Manuel; Santamaria, J. (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Conference report
    Open Access
    Linear and non-linear measures applied to heart rate variability (HRV) can be used to quantify modulation of the sympathetic and parasympathetic branches of the autonomic nervous system. RR signals were obtained from the ...
