Claim 3:
4. The medical device of claim 3, wherein to determine the time-varying measurement of CSD corresponding to each electrode of the plurality of electrodes, the processing circuitry is further configured to:
determine, for each electrode of the plurality of electrodes, a respective first time-varying measurement based on a second-order voltage difference between two electrodes of the plurality of electrodes that horizontally neighbor the respective electrode and a horizontal distance between the two horizontally neighboring electrodes;
determine, for each electrode of the plurality of electrodes, a respective second time-varying measurement based on a second-order voltage difference between two electrodes of the plurality of electrodes that vertically neighbor the respective electrode and a vertical distance between the two vertically neighboring electrodes; and
determine the respective time-varying measurement of the CSD based on the respective first time-varying measurement and the respective second time-varying measurement.
