A medical device is configured to deliver an electrical stimulation pulse to a heart of a patient, determine a pre-stimulation cardiac event amplitude prior to delivering the electrical stimulation pulse and adjust a cardiac event sensing threshold according to a first post-stimulation decay sequence in response to the electrical stimulation pulse delivery. The first post-stimulation decay sequence is controlled by a sensing module of the medical device according to a first set of sensing control parameters including at least one sensing control parameter based on the pre-stimulation cardiac event amplitude.
