Classification: CPC A | IPC A

Claim 0:
1. A system, comprising:
a plurality of electrodes positioned within a patient, the plurality of electrodes including an active electrode, the active electrode configured to be a cathode electrode located proximate to tissue of interest that is associated with a target region;
an anode electrode;
an antenna;
a control circuit configured to control delivery of a therapy during a therapy delivery interval, the therapy to be delivered between the 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;
a regulator circuit connected to the cathode electrode, the regulator circuit configured to control at least one of voltage or current at the cathode electrodes;
during a discharge operation, the control circuit configured to manage the CR circuit to control 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; and
during the discharge operation, the regulator circuit configured to regulate at least one of the discharge voltage or current through the active electrode based on an electromagnetic interference (EMI) feedback signal, to maintain the AEPD profile over the discharge operation while in a presence of an EMI event.
