1. Apparatus comprising:
a ventricular assist device comprising:
an impeller configured to be placed inside a left ventricle of a subject;
a motor unit configured to be disposed outside the body of the subject, and comprising:
a motor;
a driving magnet coupled to the motor and configured to be rotated by the motor;
a driven magnet magnetically coupled to the driving magnet and being configured to be rotated by the driving magnet;
a drive cable extending from the driven magnet and configured to impart rotational motion from the driven magnet to the impeller;
a set of sensors configured to detect a magnetic phase difference between the driven magnet and the driving magnet; and
a computer processor configured to receive the detected magnetic phase difference and to determine a physiological parameter of the subject, at least partially in response thereto.
