An apparatus comprises a cardiac signal sensing circuit configured to sense an electrical cardiac signal from at least one of an atrium or ventricle of a heart of a subject, a therapy circuit configured to provide electrical pacing therapy and electrical autonomic neural modulation therapy to the subject, and a control circuit. The control circuit is configured to initiate delivery of the autonomic modulation neural therapy, and the control circuit includes a signal detection circuit configured to detect delivery of the autonomic neural modulation therapy in the sensed cardiac signal. The control circuit is configured to change, in response to detecting the delivery, a sensitivity of the cardiac signal sensing circuit during delivery of the autonomic neural modulation therapy.
