Active medical device, in particular implantable device such as pacemaker, defibrillator, cardioverter or multisite device, having means for detecting sleep disorders

摘要

The implantable equipment which may be a stimulator, defibrillator or multi-site device includes means to capture the cardiac rate from a heart cavity and analyze it to evaluate the cardiac frequency. The means are able to identify spontaneous events and analyze cardiac frequencies over time to determine the presence of sleeping disorders. The analysis may operate by studying bradycardiac/tachycardiac episodes or frequency variations
