1. A method of pacing a His bundle of a patient heart using a stimulation system, the stimulation system having a pulse generator, a stimulating electrode disposed in proximity to the His bundle, at least one sensing electrode adapted to sense electrical activity of the patient heart, and a memory, the method comprising:
initializing one or more output settings of the stimulation system, wherein initializing the output settings comprises:
accessing a table stored in the memory, the table including a plurality of entries, each entry including a respective output setting and a respective classification, the classification indicating whether the output setting results in capture of one or both of the His bundle and a ventricle of the patient heart;
identifying, from the table, a lowest-energy output setting classified as resulting in capture of at least the His bundle or, if no impulse is classified as resulting in capture of the His bundle, as resulting in capture of the ventricle;
configuring the output settings of the stimulation system based on the lowest-energy output setting; and
applying, using the stimulation electrode, an impulse to the patient heart using the output settings.
