      abstract = {A controller is provided to determine a ventricular  filling phase slope as an indicator of high pulmonary  capillary wedge pressure and/or cardiac index. Flow rate  values describing a blood flow rate through a ventricular  assist device are received. A ventricular filling phase  segment is identified from a portion of the received flow  rate values. A slope of the received flow rate values  during the identified ventricular filling phase segment is  determined. The determined slope is compared to a  predetermined threshold value. When the determined slope  exceeds the predetermined threshold value based on the  comparison, a warning is triggered regarding an elevated  pulmonary capillary wedge pressure or a low cardiac index  value.},
