Patent ID: 11918377
Assignee: MEDTRONIC, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 16:
17. A method comprising;
delivering, by first circuitry of a medical device, an impedance measurement signal via a first electrode and a second electrode, wherein the impedance measurement signal is configured to induce a voltage on skin of a patient;
sensing, by second circuitry of the medical device, the induced voltage via third electrode and a fourth electrode,
wherein each of the first electrode, the second electrode, the third electrode, and the fourth electrode is configured to be placed in contact with the skin of the patient and held in position with a compressive member that is free of adhesives,
wherein the third electrode surrounds the first electrode,
wherein the fourth electrode surrounds the second electrode,

receiving, by processing circuitry of the medical device, an output from the second circuitry;
determining, by the processing circuitry, a biological impedance of the patient based at least on the received output; and
measuring and analyzing, by the processing circuitry, an electrocardiogram of the patient based on the received output, wherein the processing circuitry is configured to simultaneously measure the electrocardiogram and determine the biological impedance.
