Abstract: Techniques are disclosed for measuring an analyte in a biological system. A system may include a medical device with an electrochemical sensor configured to sense the concentration of a plurality of analytes present in a biological system. Processing circuitry of the system may retrieve, identify, and process a respective signal from a respective work electrode to determine the concentration of a respective analyte. The system may further include an implantable medical device configured to sense a cardiac electrogram (EGM). In some examples, the system may be configured to determine one or more patient-specific relationships between the respective signals of the electrochemical sensor and the cardiac EGM during a first period of time. Based on the patient-specific relationships, the system may estimate concentrations of the one or more analytes corresponding to the respective signals based on the cardiac EGM of the patient collected over a second period of time.
