Abstract
The present disclosure provides for methods and devices for determining the probability of a patient's aortic valve being open or closed. In one embodiment, a plurality of flow rate data points are obtained from a blood pump, a portion of the flow rate data points are identified, first and second index values characterizing properties of at least part of the identified portion of the flow rate data points determined using only arithmetic and/or exponentiation operations, and a probability is determined of whether the patient's aortic valve is open or closed based on the first and second index values.
