1. A system for pacing a heart, comprising:
an electrostimulation circuit configured to generate electrostimulation pulses to stimulate a His bundle or a bundle branch of the heart;
a sensing circuit configured to sense a far-field ventricular activation using at least a chest electrode; and
a control circuit, including a capture verification circuit configured to:
determine a cardiac synchrony indicator using the sensed far-field ventricular activation in response to the electrostimulation of the His bundle or the bundle branch; and
verify a capture status using the determined cardiac synchrony indicator.
