Classification: CPC A | IPC A

Claim 9:
10. A method comprising:
generating, by sensing circuitry of an implantable medical device system, signals representing activity of a heart of a patient;
determining, by processing circuitry of the implantable medical device system, based on the signals, an intrinsic delay of the heart of the patient;
determining, by the processing circuitry, whether the intrinsic delay is indicative of a first-degree heart block being present in the heart of the patient based on whether the intrinsic delay is less than a threshold;
administering, by therapy delivery circuitry of the implantable medical device system, a pacing pulse to the native conduction system of the heart of the patient;
determining, by the processing circuitry, a pace-activation delay based on the signals, wherein the pace-activation delay indicates a time between delivery of the pacing pulse and an earliest onset of ventricular activation;
determining, by the processing circuitry, a patient-specific timing regime for conduction system pacing based on the intrinsic delay, whether the intrinsic delay is indicative of the first-degree heart block being present in the heart of the patient, and the pace-activation delay, wherein to determine the patient-specific timing regime, the processing circuitry is configured to, based on the intrinsic delay not being indicative of the first-degree heart block being present in the heart of the patient, determining, by the processing circuitry, the patient-specific timing regime based on a minimum of: (i) a coefficient multiplied by the intrinsic delay, and (ii) a difference between the intrinsic delay and the pace-activation delay; and
administering, by the therapy delivery circuitry, cardiac pacing to a native conduction system of the heart of the patient based on the patient-specific timing regime.
