Abstract: The present disclosure provides for each of a method of characterizing divergence of a monitored flow rate of blood through an implantable blood pump, and a method of predicting an upcoming adverse cardiac event using operating data of the blood pump, such as the characterized divergence data. Predicting an upcoming adverse cardiac event may be further based on similar operating data from a plurality of other implantable blood pumps.

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.
