      Physical activity (PA) has been identified as a key health indicator and has been assessed in multiple studies as the study of cardiovascular diseases, diabetes mellitus, obesity and psychological conditions. For this ...
    • Muscle fatigue monitoring using a multifrequency bioimpedance technique 

      Vescio, Giovanni; Rosell Ferrer, Francisco Javier; Nescolarde Selva, Lexa Digna; Giovinazzo, Giuseppe (Springer, 2011)
      Conference report

      The objective of this work is to measure the changes of electrical bioimpedance module and phase related to muscular fatigue. The results could also be interesting for medical diagnosis of leg oedema, related to heart ...
    • The feasibility of transoesophageal bioimpedance measurements for the detection of heart graft rejection 

      Giovinazzo, Giuseppe; Ribas, Núria; Cinca, J.; Rosell Ferrer, Francisco Javier (IOP PUBLISHING LTD, 2011-07)
      Article
      Restricted access - publisher's policy
      Previous studies demonstrate that it is possible to evaluate a heart graft rejection condition using a bioimpedance technique by means of an intracavitary catheter. We propose to use a less invasive technique consisting ...
    • 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)
      Conference report
      Open Access
      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)
      Conference report
