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.

Abstract: A method of detecting a disruption in a diurnal rhythm of a patient having an implantable blood pump comprising 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 and generating an alert when the calculated MACD does not cross a MACD zero line for a predetermined MACD zero line crossing time threshold.

Abstract: A method of predicting an adverse event in a patient having an implantable blood pump including correlating a pulsatility value to a flow trough value associated with the blood pump to determine a flow peak value; dividing the determined flow peak value by a pump current to determine a pulsatility peak value; tracking a first moving average of the pulsatility peak value, the first moving average defining a threshold range; tracking a second moving average of the pulsatility peak value, the second moving average being faster than the first moving average; and generating an alert when the second moving average deviates from the threshold range.
