Abstract: Described herein are implantable medical devices (IMDs), and methods for use therewith. In certain embodiments, a controller of an IMD controls when a pacing capacitor of the IMD is charged using a first voltage, when the pacing capacitor is being charged using a second voltage, and when the pacing capacitor is discharged to deliver a pacing pulse between anode and cathode electrodes of, or electrically coupled to, the IMD. By selectively charging the pacing capacitor for a portion of a charge duration using the second voltage, that is greater in magnitude than the first voltage that is used for delivering the pacing pulse, a magnitude of a polarization artifact superimposed on an evoked response within a cardiac electrical signal, sensed using a sensing circuit of the IMD, is reduced compared to if the pacing capacitor were instead charged using the first voltage for the entire charge duration.

Abstract: The present disclosure provides systems and methods for applying anti-tachycardia pacing (ATP) using subcutaneous implantable cardioverter-defibrillators (SICDs). An SICD implantable in a subject includes a case including a controller, and at least one conductive lead extending from the case. The at least one conductive lead includes a plurality of coil electrodes, wherein the SICD is configured, via the controller, to apply anti-tachycardia pacing (ATP) to the subject using the at least one conductive lead.
