摘要:
A monitoring system senses a physiological signal indicative of mechanical vibrations including audible and/or subaudible frequency ranges and presents information related to the physiological signal to a user. The presented information includes subaudible components of the physiological signal. In various embodiments, the information can be presented as a visual signal representing the mechanical vibrations including the subaudible components, an audial signal representing the mechanical vibrations having a spectrum shifted to an audible frequency range, and/or an audial signal representing the mechanical vibrations having a spectrum compressed into an audible frequency range. An example of the physiological signal can include a heart sound signal indicative of heart sounds including cardiac mechanical vibrations in audible and subaudible frequency ranges.
