METHOD AND APPARATUS FOR DETERMINING AORTIC VALVE OPENING

摘要

Apparatus for determining opening of an aortic valve of a biological subject, the apparatus including an electronic processing device that determines a pump speed of a ventricular assist device that is assisting cardiac function of the biological subject, analyses the pump speed to determine a pump speed indicator at least partially indicative of changes in pump speed and uses the pump speed indicator to determine an opening indicator indicative of opening of the aortic valve.
