Abstract
A method determining adverse events from operation of an implantable blood pump including calculating a moving average convergence divergence (MACD) based on power consumed by the implantable blood pump to maintain a constant rotational speed of an impeller of the implantable blood pump. An alert is generated when the calculated MACD diverges from a predetermined MACD threshold and a predetermined MACD zero-crossing time threshold.
