1. A method of controlling operation of a ventricular assist device (VAD) implanted within a patient having a heart, the method comprising:
maintaining attachment of a housing of the VAD to a ventricular heart wall of the heart so that motion of the ventricular heart wall is transferred to the housing;
processing, by a controller, output of an accelerometer supported by the housing to measure accelerations of the VAD, wherein the VAD comprises the accelerometer;
processing, by the controller, the accelerations of the VAD to measure at least one of a respiratory activity of the patient or a cardiac cycle timing of the patient; and
controlling, by the controller, operation of the VAD based on at least one of the respiratory activity or the cardiac cycle timing.
