摘要： A blood circulation assist system includes a ventricular assist device (VAD) and a controller. The VAD is attachable to a heart of a patient to pump blood from a ventricle of the heart into a blood vessel of the patient. The VAD includes an impeller, a motor stator operable to rotate the impeller, and an accelerometer generating an accelerometer output indicative of accelerations of the VAD. The controller controls operation of the motor stator to control rotational speed of the impeller based on the accelerometer output.
