      Text en actes de congrés
      Accés obert
      In this paper, a novel implantable bioimpedance monitor using a free ZigBee protocol for the transmission of the measured data is described. The application field is the tissue and organ monitoring through electrical ...

    • Influence of respiration in the very low frequency modulation of QRS slopes and heart rate variability in cardiomyopathy patients 

      Hernando, David; Alcaine, A; Pueyo, Esther; Laguna, Pablo; Arcentales, Andrés; Giraldo Giraldo, Beatriz; Voss, Andreas; Bayés-Genís, Antoni; Bailón, Raquel (2013)

      Accés restringit per política de l'editorial
      This work investigates the very low frequency (VLF) modulation of QRS slopes and heart rate variability (HRV). Electrocardiogram (ECG) and respiratory flow signal were acquired from patients with dilated cardiomyopathy and ...

    • Longitudinal and transversal bioimpedance measurements in addition to diagnosis of heart failure 

      Ribas, N.; Nescolarde Selva, Lexa Digna; Domingo, M.; Gastelurrutia, P.; Bayés-Genís, Antoni; Rosell Ferrer, Francisco Javier (2010)
      Text en actes de congrés
      Accés obert
      Heart Failure (HF) is a clinical syndrome characterised by signs of systemic and pulmonary fluid retention, shortness of breath and/or fatigue. There is a lack of reliable indicators of disease state. Benefits and ...
