Abstract
A system includes a sensor and a processor. The sensor is configured to generate hemodynamic information for a patient. The processor is configured to execute instructions to calculate spectral content using the hemodynamic information. The processor is configured to generate an output signal based on the calculated spectral content. The calculated spectral content includes a fundamental component and at least one harmonic component. The spectral content corresponds to at least one of amplitude and frequency. The output signal corresponds to a state of the patient or corresponds to an operational parameter of a cardiac assist device associated with the patient.
