Cardiac device placement and verification aid

An RF-based physiological monitoring device placement verification system, comprising:

• a patch configured to be adhesively coupled to skin of a patient;
• an RF sensor configured to be mechanically coupled to the patch, the RF sensor comprising
• at least one radio frequency (RF) antenna and associated transmitter/receiver circuitry configured to transmit RF waves into and receive reflected RF waves from a body of the patient;
• and
• at least one processor in electrical communication with the at least one radio frequency (RF) antenna and associated transmitter/receiver circuitry, the at least one processor configured to
• generate first one or more RF metric signals during a first period of time based on at least one of the transmitted or reflected RF waves associated with a prescribed anatomical location of the patch on the body of the patient, wherein the first one or more RF metric signals is configured for determining first one or more thoracic fluid parameters of the patient;
• generate second one or more RF metric signals during a second period of time subsequent to the first period of time based on at least one of the transmitted or reflected RF waves associated with a re-placement of the patch at a proposed anatomical location of the body of the patient,
• analyze the first and second one or more RF metric signals to determine a re-placement score associated with the re-placement of the patch at the proposed anatomical location of the body of the patient;
• determine whether the re-placement score transgresses a predetermined threshold value;
• and
• provide an alert indicating whether the re-placement of the patch at the proposed anatomical location is acceptable based on whether the placement score does not transgress the predetermined threshold value.
