Cardiovascular Perturbations Involved in Periodic Leg Movements during Sleep

摘要

The nocturnal PLM disease is not well known, especially in its relationship with cardiovascular (CV) rhythms. To address this question, we processed a standard poiysomnographic recording in a typical patient, in the LARY_C software: a time-frequency analysts, using the Smoothed Pseudo Wigner-Ville Transform was done to follow the Autonomic Nervous System (ANS) behavior through the short time variations accompanying a PLM on Heart Rate (HR) and Arterial Blood Pressure (ABP); 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 are so quantified and the study of delays between CV and motor perturbations reveals new possible tnsigths on the PLM physiopathology.
