Title
(EN) METHOD AND SYSTEM FOR MEASURING AORTIC PULSE WAVE VELOCITY
(FR) PROCÉDÉ ET SYSTÈME DE MESURE DE LA VITESSE DE L'ONDE DE POULS AORTIQUE
Abstract
(EN)
The present invention relates to a method and system for determining the aortic pulse wave velocity. The method comprises receiving an indication of a measurement of a length of a human aorta to provide an aortic length, arranging a first and second sound transducer outside the body of the patient, and identifying the opening of the aortic valve with measurement from the first sound transducer as a first time, and the pulse wave arrival time at the aortic bifurcation with measurements from the second sound transducer as a second time. The aortic transit time is determined based on the difference between the second time and the first time, and the aortic pulse wave velocity is calculated based on the aortic length and the aortic transit time.

La présente invention concerne un procédé et un système permettant de déterminer la vitesse de l'onde de pouls aortique. Le procédé comprend la réception d'une indication d'une mesure de la longueur d'une aorte humaine pour fournir une longueur aortique, l'agencement d'un premier et d'un second transducteur sonore à l'extérieur du corps du patient, et l'identification de l'ouverture de la valvule aortique avec une mesure provenant du premier transducteur sonore en tant que premier temps, et le temps d'arrivée de l'onde de pouls au niveau de la bifurcation aortique avec des mesures provenant du second transducteur sonore en tant que second temps. Le temps de transit aortique est déterminé sur la base de la différence entre le second temps et le premier temps, et la vitesse de l'onde de pouls aortique est calculée sur la base de la longueur aortique et du temps de transit aortique.
