In the last years the home monitoring development is increased both for its capability as a real time tool to manage patients health and to reduce hospitalization costs. The home monitoring system is a complex structure that needs the collaboration of different disciplines, from medicine to engineering, and technologies. This project has been developed with the integration of different groups of research...
The purpose of this work is to characterize the heart rate variability (HRV) of patients affected by congestive heart failure (CHF) and to find out the main difference between this pathological condition and the physiological state. Parameters adopted in this work are: the detrended fluctuation analysis (DFA) and the Higuchi exponent to assess long correlations and self-similarity; the regularity...

A "managed care" model (prevention, diagnosis, therapy, admission, home assistance) has been realized to permit both a continuous patients check without hospitalization and a patients data archiving. An hardware and software architecture has been designed to manage the out-of-hospital treatments of patients with a moderate cardiovascular risk; as all the sensors built are wearable the cardio...
The complex structure of the heart rate variability signal (HRV) has been widely studied in order to identify the "complex" nature of its control mechanisms. By adopting methods based on the reconstruction of the HRV time series, in an embedding space, the fractal dimension and the Lyapunov exponents can be computed. These estimations must be associated to a determinism test based on surrogate...
