Time–frequency analysis of time-varying in vivo myocardial impedance Vrije Universiteit Brussel
The frequency response identification of a (bio-)system that is inherently nonlinear and time-varying, e.g. in vivo myocardial impedance, through electrical impedance spectroscopy (EIS) is still a task in progress today that deserves further research. In this work, the in-cycle time-varying behavior of in vivo myocardium is modeled by means of Fricke-Morse's circuit model. Temporal changes in the in vivo myocardial impedance during the cardiac ...
