Monitoring physiological status based on bio-vibrational and radio frequency data analysis

A system for monitoring physiological parameters of a patient, the system comprising:

• an externally worn cardiac monitor configured to be bodily-attached to a patient during a prescribed period of use, the externally worn cardiac monitor comprising:
• an electrocardiogram sensor configured to detect one or more electrocardiogram signals of the patient,
• a microphone configured to detect one or more cardio-vibrational signals of the patient,
• a radiofrequency transceiver circuit comprising one or more antennas configured to direct radiofrequency energy into the patient, wherein the radiofrequency transceiver circuit is configured to produce radiofrequency information responsive to reflected radiofrequency energy that is reflected from within the patient and received through the one or more antennas, and
• one or more device processors configured to
• during a monitoring interval within the prescribed period of use, process the one or more electrocardiogram signals and the one or more cardio-vibrational signals to generate electromechanical activation parameter data for the monitoring interval, and
• during the monitoring interval, process the radiofrequency information to generate thoracic fluid content data for the monitoring interval;
• and
• a remote server comprising one or more server processors and a network interface, the one or more server processors configured to:
• receive, via the network interface, the electromechanical activation parameter data and the thoracic fluid content data for the monitoring interval,
• perform a trend analysis on the electromechanical activation parameter data and the thoracic fluid content data to identify a substantial relationship between the electromechanical activation parameter data and the thoracic fluid content data, and
• cause an output device to provide a first output representing at least a first portion of the monitoring interval, wherein the first output visually depicts the substantial relationship.
