Device for determining a characteristic point in the cardiac cycle, which device comprises means for calculating the curve of the blood flow rate D(t) in the aorta from the curve of the arterial blood pressure signal P(t) and determining from the curve of the blood flow rate D(t) in each cardiac cycle the time at which the incisura point lies. The device can be used for activating an intra-aortal balloon pump (IABP).

La présente invention concerne un appareil servant à déterminer un point caractéristique du cycle cardiaque. Cet appareil comporte un dispositif permettant de calculer la courbe du débit sanguin D(t) dans l'aorte à partir de la courbe du signal de pression artérielle P(t) et de déterminer, à partir de la courbe ainsi calculée D(t), dans chaque cycle cardiaque, le point d'échancrure. Cet appareil peut être utilisé pour mettre en marche une pompe à ballon intra-aortique.
