Classification: CPC A | IPC A

Claim 10:
11. A method, comprising:
providing a plurality of electrodes to be located proximate to tissue of interest that is associated with a target region, the plurality of electrodes including an active electrode configured to be a cathode electrode;
delivering a therapy during a therapy delivery interval between an anode electrode and the active electrode, the system developing a residual charge between the anode electrode and the active electrode over the therapy delivery interval; and
during a discharge operation in a presence of an EMI event:
controlling at least one of a discharge voltage or current over the discharge operation to discharge the residual charge after therapy delivery in a manner that follows an actively emulated passive discharge (AEPD) profile;
obtaining an electromagnetic interference (EMI) feedback signal from an antenna while in the presence of the EMI event; and
regulating the at least one of a discharge voltage or current at the anode and cathode electrodes based on the EMI feedback signal to maintain the AEPD profile over the discharge operation while in the presence of the EMI event.
