Device for determining a charasteristic point in the cardiac cycle

摘要

The present invention relates to a device for determining a characteristic point in the cardiac cycle that 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 an [the] incisura point lies. The device can be used for activating an intra-aortal balloon pump (IABP).
