Claim 0:
1. A mechanical circulatory assist system comprising:
a continuous-flow pump comprising a centrifugal rotor configured to generate a centrifugal flow, wherein the continuous-flow pump is adapted to pump blood from a left ventricle of a heart of a patient to an aorta of the patient to assist blood flow from the left ventricle to the aorta; and
a controller comprising a sensor that generates a signal indicative of a power consumption of the continuous-flow pump, wherein the controller is operatively connected to the continuous-flow pump and configured to operate the continuous-flow pump in an artificial pulse mode comprising recurring changes in a rotational speed of the continuous-flow pump, wherein at least one of the recurring changes in the rotational speed of the continuous-flow pump are synchronized with contractions of the left ventricle, wherein the controller comprising a processor configured to detect, based on a speed of the continuous-flow pump and the power consumption of the continuous-flow pump, the contractions of the left ventricle.
