1. A system for pacing a heart, comprising:
an electrostimulation circuit configured to generate stimulation pulses for delivery at one or more target sites; and
a control circuit configured to receive a cardiac activity, the control circuit including:
a capture verification circuit configured to detect a His-bundle capture status using the received cardiac activity; and
a pacing control circuit configured to control the electrostimulation circuit to:
receive a programmed atrial-to-ventricular conduction delay distinct from an intrinsic atrial-to-His bundle interval;
generate a His-bundle pacing (HBP) pulse and deliver the HBP pulse after a time interval shorter than the programmed atrial-to-ventricular conduction delay subsequent to an atrial activity to capture a His-bundle of the heart; and
generate a left-ventricular pacing (LVP) pulse to capture a left ventricle of the heart if the detected His-bundle capture status, in response to the HBP pulse, satisfies a specific condition.
