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 a first output electric signal and a second output electric signal, and transmitting said first output signal to an organ at a first part of the body of the subject and said second output signal to an organ at a second part of the body of the subject; a demodulation system configured for receiving a first input electrical signal sensed from said first part of the body and a second input electrical signal sensed from said second part of the body, and for demodulating each input electrical signal to provide an in-phase component and a quadrature component of each input signal; a signal processing system having a circuit for combining a respective in-phase component and a respective quadrature component of each input signal, to respectively provide a first hybrid signal and a second hybrid signal, and for generating a graphical output co-displaying said hybrid signals.
