ACTIVE IMPLANTABLE MEDICAL DEVICE COMPRISING A FUNCTION FOR MONITORING SYMPATHIC-VAGAL ACTIVITY BY ANALYZING ENDOCARDIAL ACCELERATION

摘要

This device comprises means for collecting at least one physiological parameter of the patient, and analysis means, receiving as input the said parameter (s) and outputting data representative of the sympathico-vagal activity of the patient. The physiological parameter is an endocardial acceleration (EA), and the representative data comprise at least one value which is a function of this endocardial acceleration, in particular a function of a first peak (PEA I) during the isovolumic ventricular contraction phase and / or a second peak (PEA II) during the isovolumic ventricular relaxation phase. / P
