1. A method of determining a position of a blood pump in a body of a patient, the method comprising:
inserting a blood pump into a heart of a patient, the blood pump having a housing, wherein the housing surrounds a rotor;
actuating the rotor;
receiving, at a processing unit, a first signal, wherein the first signal represents a rotational speed of the rotor;
determining, at the processing unit, based on the first signal, a flow velocity of a periodic blood flow through the blood pump;
determining, at the processing unit, a phase angle of the periodic blood flow;
detecting, at a main sensor having a constant position relative to the blood pump, a second signal, wherein the second signal is indicative of a cardiac parameter; and
determining, from the phase angle of the periodic blood flow and the second signal, the position of the blood pump within the body of the patient.
