Method and system for monitoring hemodynamics

摘要

A system for monitoring hemodynamics of a subject is disclosed. The system comprises: a signal generating system configured for providing at least an output electric signal and transmitting the output signal to an organ of the subject. The system also comprises a demodulation system configured for receiving an input electrical signal sensed from the organ responsively to the output electric signal, and for modulating the input signal using the output signal to provide an in-phase component and a quadrature component of the input signal. The system also comprises a processing system configured for monitoring the hemodynamics based on the in-phase and the quadrature components.

1. A system for monitoring hemodynamics of a subject, comprising:
a signal generating system configured for providing at least an output electric signal and transmitting said output signal to an organ of the subject; a demodulation system configured for receiving an input electrical signal sensed from the organ responsively to said output electric signal, and for modulating said input signal using said output signal to provide an in-phase component and a quadrature component of said input signal; a processing system configured combine said in-phase component with said quadrature component thereby to generate a hybrid signal, and for monitoring the hemodynamics based at least in part on said hybrid signal wherein said hybrid signal comprises a linear combination of said components.
