    • 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 ...

    • Transoesophageal detection of heart graft rejection by electrical impedance: using Finite Element Method simulations 

      Giovinazzo, Giuseppe; Ribas, N.; Cinca, J.; Rosell Ferrer, Francisco Javier (2010)
      Text en actes de congrés
      Accés obert
      Previous studies have shown that it is possible to evaluate heart graft rejection level using a bioimpedance technique by means of an intracavitary catheter. However, this technique does not present relevant advantages ...

    • Transoesophageal electrical bioimpedance measurements of the heart in humans 

      Giovinazzo, Giuseppe; Raga, S.; Ribas, N.; Bayés-Genís, Antoni; Cinca, J.; Rosell Ferrer, Francisco Javier (Springer Verlag, 2009-09)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Previous studies have proved that posttransplant cardiac rejection is associated with changes in endomyocardial electrical impedance in humans. The aim of this study is to develop a safe transoesophageal system able to ...
