A method, system and computer readable medium for deriving central aortic systolic pressure by reversing the order of a set of predetermined number of blood pressure measurements to obtain a reversed blood pressure set; averaging the reversed blood pressure set such that the average set represents a moving average waveform; overlaying the reversed blood pressure set and the moving average waveform; identifying a point of intersection on the reversed arterial waveform and the moving average waveform, and setting the central aortic systolic pressure as a reversed blood pressure value in the reversed blood pressure set nearest to the point of intersection.
La présente invention concerne un procédé, un système et un support lisible sur ordinateur pour dériver une pression systolique aortique centrale par inversion de lordre dun ensemble dun nombre prédéterminé de mesures de pression artérielle pour obtenir un ensemble inversé de pressions artérielles; calculer la moyenne de lensemble inversé de pressions artérielles de sorte que lensemble moyenné représente une forme donde mobile de la moyenne; superposer lensemble inversé de pressions artérielles et de la forme donde mobile de la moyenne; identifier un point dintersection sur la forme donde artérielle inversée et la forme donde mobile de la moyenne, et définir la pression systolique aortique centrale comme étant une valeur de pression artérielle inversée dans lensemble inversé de pressions artérielles à proximité du point dintersection.
