Abstract :
The nocturnal periodic leg movements (PLM) disease is not well known, especially in its relationship with cardiovascular (CV) rhythms. To address this question, the authors processed a standard polysomnographic recording in a typical patient, using the LARY-C software. A time-frequency analysis, using the smoothed pseudo Wigner-Ville transform was done to follow the autonomic nervous system (ANS) behavior through the short time variations of heart rate (HR) and arterial blood pressure (ABP) accompanying a PLM. The synchronous language SIGNAL, well suited for studying relationships between rhythms, was used to automatically produce a set of cardiovascular parameters related to a PLM. Important CV changes were quantified. The study of delays between CV and motor perturbations reveals new possible insights on PLM physiopathology.
