Nonlinear analysis of cardiological signals towards clinical applications
- P.-A. Absil
This work is dedicated to the study of cardiac rhythm. It results from a
collaboration with the Cardiology and Neurology Departments at Liège
University Hospital. The applications considered are essentially twofold: on
the one hand, prognosis regarding the health of patients suffering from
congestive heart failure, through studying long range correlations and
scale invariance in their cardiac rhythm; one the other hand, diagnosis of
sleep apnea by means of a dedicated processing of the patient's cardiac
rhythm. Both studies are based on the so-called RR signal, i.e., the
sequence of time intervals between successive ventricular contractions.
