10. A blood pump for supporting a heart, the blood pump comprising:
a rotor with delivery elements;
a rotor drive;
a pressure sensor;
a regulating device configured to regulate a pressure by control of the rotor drive, wherein the regulating device is configured to regulate a specific pressure parameter successively to different target values; and
wherein the regulating device is configured to regulate to varying target values during operation of the rotor drive such that at least one prespecified feature of a temporal curve of the pressure, a flow, a motor current, or a bearing position is attained.
