Abstract
A method of determining a heart rate of a patient having an implanted blood pump including applying a voltage to a plurality of coils of a stator of the blood pump to produce an electromagnetic force to rotate a rotor in communication with the plurality of coils; displaying a waveform associated with a back electromotive force in the plurality of coils of the blood pump, the waveform being proportional to an axial position of the rotor relative to the stator; determining a time interval between a first alteration in the waveform relative to a baseline and a second alteration in the waveform relative to the baseline; and determining the heart rate of the patient based on the time interval.
