Abstract:
1. A system for monitoring a patient and presenting diagnostic information to a user, the system comprising: a vibration sensor configured to sense a physiological signal indicative of mechanical vibrations in a sensing frequency range including audible and subaudible frequency ranges; a further sensor configured to sense a further physiological signal; a processing circuit coupled to the vibration sensor, the processing circuit configured to produce one or more presentation signals representing the mechanical vibrations in a presentation frequency range including at least one subaudible frequency range of the sensing frequency range using the physiological signal and the further physiological signal; and a user interface coupled to the processing circuit, the user interface configured to present the one or more presentation signals to the user, wherein the further sensor includes electrocardiographic electrodes configured to sense an electrocardiographic signal, and the processing circuit includes a signal conditioning circuit configured to perform ensemble averaging of the heart sound signal using the ECG signal.
