Abstract: 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.

Abstract: A cardiac monitoring system for displaying contextual biometric information for arrhythmia events occurring in a patient is provided. The system includes a cardiac sensor configured to be coupled to the patient. The cardiac sensor is configured to transmit ECG signals and motion signals to a remote server. The remote server is in communication with the cardiac sensor and further in communication with a user interface. The remote server includes a database implemented in a non-transitory memory and a processor in communication with the database. The processor is configured to store the ECG signals and the motion signals in the database and identify an arrhythmia event based on the received ECG signals. The processor is also configured to determine, based on the motion signals, contextual biometric information of the patient for the arrhythmia event and display, on the user interface, the arrhythmia event with the contextual biometric information of the patient.
