1. A medical device system, comprising:
an implantable medical device comprising:
a sensing circuit configured to sense a cardiac electrical signal;
a therapy delivery circuit configured to deliver pacing pulses according to a first pacing output control parameter; and
a control circuit coupled to the sensing circuit and the therapy delivery circuit and configured to:
receive an indication of effective or partial His bundle capture, the indication being a wirelessly transmitted notification signal;
determine confirmed effective or partial His bundle pacing at the pacing output control parameter based on the received indication of effective or partial His bundle capture;
in response to receiving the wirelessly transmitted notification signal as the indication of effective or partial His bundle capture, determine a feature of the cardiac electrical signal sensed by the sensing circuit during the confirmed effective or partial His bundle pacing at the pacing output control parameter; and
establish a corresponding effective or partial His bundle capture detection threshold based on the determined feature of the cardiac electrical signal sensed by the sensing circuit during the confirmed effective or partial His bundle pacing.
