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.
