ESTIMATION OF SERUM POTASSIUM AND/OR GLOMERULAR FILTRATION RATE FROM ELECTROCARDIOGRAM FOR MANAGEMENT OF HEART FAILURE PATIENTS

Abstract: this disclosure is directed to devices, systems, and techniques for estimating a serum potassium level. an example system includes a plurality of electrodes, sensing circuitry configured to sense an ecg of a patient, and processing circuitry. the processing circuitry is configured to determine a t-wave morphology in the ecg and based on the t-wave morphology, determine an estimate of serum potassium in blood of the patient. the processing circuitry is configured to determine that the estimate of serum potassium in the blood satisfies a threshold and based on the estimate of serum potassium in the blood satisfying the threshold, generate an indication for output that is based at least in part on the estimate of serum potassium in the blood satisfying the threshold.
