摘要：
A method of determining adverse events from log file data from operation of an implantable blood pump. The method includes measuring a flow pulsatility from flow rate data recorded in a log file. A moving mean of the measured flow pulsatility is calculated. A moving standard deviation of the measured flow pulsatility is calculated. A difference between the moving mean of the measured pulsatility and the moving standard deviation of the measured flow pulsatility is calculated. If the difference is less than a first predetermined threshold, an alert is generated as the presence of an adverse event.
