Abstract
The invention refers to a monitoring device for monitoring and analyzing physiological signals. The monitoring device comprises a transthoracic impedance measurement unit and an evaluation unit connected to the transthoracic impedance measurement unit. The transthoracic impedance measurement unit is adapted to conduct a transthoracic impedance measurement and to generate a transthoracic impedance signal representing a measured transthoracic impedance at consecutive points in time. The evaluation unit being configured to process the transthoracic impedance signal received from the transthoracic impedance measurement unit and to thus generate a respiration signal and to generate therefrom an evaluation signal reflecting at least a diurnal pattern of the respiration rate.
