1. An intravascular blood pump system comprising:
an intravascular blood pump comprising:
a catheter having a proximal end and a distal end;
a pump housing coupled to the distal end of the catheter;
a rotor positioned at least partially in the pump housing, the rotor configured to be rotatably driven; and
a cannula coupled to the pump housing;
an electrode coupled to the intravascular blood pump such that the electrode is carried into a patient's heart by the intravascular blood pump when the intravascular blood pump is positioned within vasculature of the patient, wherein the electrode is configured to sense an electrocardiogram (EKG) signal of a patient's heart; and
a reference electrode coupled to the catheter, wherein the EKG signal is representative of a difference in electrical potential between the electrode and the reference electrode.
