    • T-wave morphology changes as surrogate for blood potassium concentration in hemodialysis patients 

      Palmieri, Flavio; Gomis Román, Pedro; Ferreira, Dina; Bergasa, Beatriz; Martín Yebra, Alba; Ahmed, Syed Hassaan; Pueyo, Esther; Mártinez, Juan Pablo; Ramírez, Julia; Laguna Lasaosa, Pablo (2019)
      Text en actes de congrés
      Accés obert
      End-stage renal disease (ESRD) patients undergoing hemodialysis (HD) are at high risk of arrhythmias and sudden cardiac death as a result of blood potassium con-centration ([K+]) changes.The aim of this study ...

    • Time-frequency analysis of the autonomic response to head-up tilt testing in Brugada syndrome 

      Calvo González, Mireia; Le Rolle, Virginie; Romero, Daniel; Béhar, Nathalie; Gomis Román, Pedro; Mabo, Philippe; Hernández, Alfredo I. (Computing in Cardiology, 2017)
      Text en actes de congrés
      Accés obert
      Cardiac events in Brugada syndrome (BS) usually occur at rest and mainly at night-time, commonly relating changes in autonomic modulation to arrhythmogenesis. A major challenge today is to differentiate symptomatic and ...

    • “Time-Warping” ponderado sobre la onda T para reducir el impacto de errores de delineación: implicaciones clínicas 

      Palmieri, Flavio; Gomis Román, Pedro; Ruiz, Jose Esteban; Ferreira, Dina; Pueyo, Esther; Mártinez, Juan Pablo; Laguna, Pablo; Ramírez, Julia (2021)

      Accés obert
      La morfología de la onda T (TW) se ha investigado para desarrollar marcadores de predicción de riesgo arrítmico específicos como ¿¿¿¿, que cuantifica el nivel de “warping” necesario para alinear temporalmente una TW con ...

    • Validity of the Polar V800 monitor for measuring heart rate variability in mountain running route conditions 

      Caminal Magrans, Pere; Sola Almirón, Fuensanta; Gomis Román, Pedro; Guasch, Eduard; Perera Lluna, Alexandre; Mont Girbau, Lluis (2018-03-01)
      Article
      Accés obert
      Purpose This study was conducted to test, in mountain running route conditions, the accuracy of the Polar V800™ monitor as a suitable device for monitoring the heart rate variability (HRV) of runners. Method Eighteen ...

    • Weighted time warping improves T-wave morphology markers clinical significance 

      Palmieri, Flavio; Gomis Román, Pedro; Ferreira, Dina; Pueyo, Esther; Martínez, Juan Pablo; Laguna, Pablo; Ramírez, Julia (Institute of Electrical and Electronics Engineers (IEEE), 2022-02-23)
      Article
      Accés obert
      Background: T-wave (TW) morphology indices based on time-warping (dw) have shown significant cardiovascular risk stratification value. However, errors in the location of TW boundaries may impact their prognostic power. Our ...

    • Weighted time warping T-wave analysis robust to delineation errors: clinical implications 

      Palmieri, Flavio; Gomis Román, Pedro; Ruiz, Jose Esteban; Ferreira, Dina; Pueyo, Esther; Martínez, Juan Pablo; Laguna, Pablo; Remírez, Julia (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      T-wave (TW) morphology has been extensively investigated to develop specific risk prediction markers like dw quantifying the level of warping needed to temporally align a TW respect to a reference one. However, TW boundaries ...
