SYSTEM FOR USING RADIOFREQUENCY AND LIGHT TO DETERMINE PULSE WAVE VELOCITY

Medical monitoring systems and techniques for remote monitoring of RF-based and light-based physiological information of a patient are provided. A system as disclosed herein includes an RF transmitter configured to be placed on a predetermined location of the patient and an RF receiver and associated circuitry configured to provide RF sensor signals including information about an RF-based aortic region waveform. The system includes at least one light source configured to be placed on the predetermined location and a light sensor and associated light sensor circuitry configured to provide light sensor signals including information about a light-based arterial waveform. The system includes a processor configured to determine a first fiducial point on the RF-based aortic region waveform, determine a second fiducial point on the light-based arterial waveform, determine a time difference parameter between the fiducial points, and determine at least a pulse wave velocity.
