Refined multiscale entropy analysis of heart period and QT interval variabilities in long QT syndrome type-1 patients
Bari, V.; Valencia, Jose Fernando; Vallverdú Ferrer, Montserrat; Girardengo, G.; Bassani, T.; Marchi, A.; Calvillo, L.; Caminal Magrans, Pere; Cerutti, Sergio; Brink, P.A.; Crotti, L.; Schwartz, P.J.; Porta, A. (2013)
Comunicació de congrés
Accés restringit per política de l'editorialThis study assesses complexity of cardiovascular control in patients affected by type-1 variant of long QT(LQT1) syndrome. Complexity was assessed by refined multiscale entropy of heart period (HP) and QT interval ... -
Refined multiscale entropy using fuzzy metrics: validation and application to nociception assessmentt
Valencia Murillo, José Fernando; Bolaños, José D; Vallverdú Ferrer, Montserrat; Jensen, Erik Weber; Porta, Alberto; Gambus, Pedro L. (2019-07-18)
Article
Accés obertThe refined multiscale entropy (RMSE) approach is commonly applied to assess complexity as a function of the time scale. RMSE is normally based on the computation of sample entropy (SampEn) estimating complexity as conditional ... -

Segmented Symbolic Dynamics for Risk Stratification in Patients with Ischemic Heart Failure, Cardiovascular Engineering and Technology
Voss, Andreas; Schroeder, Rico; Caminal Magrans, Pere; Vallverdú Ferrer, Montserrat; Brunel, Helena; Cygankiewicz, I.; Vázquez, Rafael; Bayes de Luna, Antonio (Springer, 2010-12-30)
Article
Accés restringit per política de l'editorialChronic heart failure (CHF) is recognized as major and escalating public health problem. Approximately 69% of CHF patients suffer from cardiac death within 5 years after the initial diagnosis. Until now, no generally accepted ... -

Symbolic dynamic analysis of relations between cardiac and breathing cycles in patients on weaning trials
Caminal Magrans, Pere; Giraldo Giraldo, Beatriz; Vallverdú Ferrer, Montserrat; Benito Vales, Salvador; Schroeder, Rico; Voss, Andreas (2010)
Article
Accés restringit per política de l'editorialTraditional time-domain techniques of data analysis are often not sufficient to characterize the complex dynamics of the cardiorespiratory interdependencies during the weaning trials. In this paper, the interactions between ... -
Symbolic dynamics of QT interval series in ischemic cardiomyopathy
Cuponne, Anna; Vallverdú Ferrer, Montserrat; Gomis Román, Pedro; Porta, Alberto; Voss, Andreas; Bayes de Luna, Antonio; Caminal Magrans, Pere (Computing in Cardiology, 2012)
Comunicació de congrés
Accés obertRepolarization dynamics may be of increasing interest in analyzing ECG-Holter for characterization of myocardial ischemic events related to cardiac death. The quantification of the dynamics of the beat-to-beat QT interval ... -
Symbolic dynamics to discriminate healthy and ischaemic dilated cardiomyopathy populations: An application to the variability of heart period and QT interval
Valencia, Jose F.; Vallverdú Ferrer, Montserrat; Rivero, Isidre; Voss, Andreas; Bayes de Luna, Antonio; Porta, Alberto; Caminal Magrans, Pere (Royal Society, 2015-02-13)
Article
Accés obertMyocardial ischaemia is hypothesized to stimulate the cardiac sympathetic excitatory afferents and, therefore, the spontaneous changes of heart period (approximated as the RR interval), and the QT interval in ischaemic ... -

Time-delay selection in poincaré plot: assessing sedation-analgesia levels with eeg signals Selección del tiempo de retardo en el gráfico de poincaré: Medición de los niveles de sedación y analgesia con señales eeg
Bolaños Jojoa, Jose Daniel; Valencia Murillo, José Fernando; Vallverdú Ferrer, Montserrat; Valencia Vargas, Daniel Felipe; Borrat, Xavier; Garnbús, Pedro Luis (2021-03-01)
Article
Accés obertEl gráfico de Poincaré es un método no lineal que permite analizar la variabilidad de una señal, dibujando dicha señal contra ella misma retardada en el tiempo. Aunque este método ha sido aplicado al análisis del ... -
Time-frequency features for impedance cardiography signals during anesthesia using different distribution kernels
Escrivá, Jesús; Gambus, Pedro L.; Jensen, Erik Weber; Vallverdú Ferrer, Montserrat (2018-01-23)
Article
Accés obertObjective: This works investigates the time-frequency content of impedance cardiography signals during a propofol-remifentanil anesthesia. Materials and Methods: In the last years, impedance cardiography (ICG) is a ... -
Transcription factor binding site detection through position cross-mutual information variability analysis
Maynou Fernández, Joan; Vallverdú Ferrer, Montserrat; Clarià Sancho, Francesc; Gallardo Chacón, Joan Josep; Caminal Magrans, Pere; Perera Lluna, Alexandre (IEEE Press. Institute of Electrical and Electronics Engineers, 2009)
Comunicació de congrés
Accés obertRegulatory sequence detection is a fundamental challenge in computational biology. One key process in protein synthesis starts with the binding of the transcription factor to its binding site. Different sites can show ...
