1. A pacing device comprising:
a set of electrodes including first, second, third, and fourth left ventricular (LV) electrodes spatially separated from one another and all coupled to an implantable pulse generator, and
a processing circuit coupled to the implantable pulse generator, the processing circuit configured to:
cause the pulse generator to deliver pacing in a pacing mode comprising delivering first pacing and second pacing pulses to a left ventricle within a single cardiac cycle using the first and second LV electrodes;
determine duration of a delay between the first and second pacing pulses;
determine whether capture has been lost at one or both of the first and second LV electrodes; and
trigger the pulse generator to modify the pacing mode in response to the determined loss of capture, wherein the modification to the pacing mode comprises:
when the determined delay between the first and second pacing pulses is greater than a preset duration, subsequently delivering pacing pulses to the left ventricle using the first and second LV electrodes separated by a delay different from the determined duration; and
when the determined delay between the first and second pacing pulses is less than or equal to the preset duration subsequently delivering pacing pulses to the left ventricle using at least one of the third and fourth LV electrodes.
