This work is dedicated to the study of cardiac rhythm. It results from a collaboration with the
Cardiology and Neurology Departments at Li`ege 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
