1. A system comprising:
an electrode apparatus comprising a plurality of external electrodes to be disposed proximate a patient's skin; and
a computing apparatus comprising processing circuitry and operably coupled to the electrode apparatus, the computing apparatus configured to:
monitor electrical activity of the patient using the plurality of external electrodes of the electrode apparatus during delivery of left bundle branch (LBB) pacing therapy,
generate electrical heterogeneity information (EHI) based on the monitored electrical activity during delivery of left bundle branch (LBB) pacing therapy,
determine a LBB pacing location for the LBB pacing therapy from a plurality of different LBB pacing locations based the EHI generated during the delivery of LBB pacing therapy at the plurality of different LBB pacing locations, and
determine an atrioventricular (AV) delay for the LBB pacing therapy from a plurality of different AV delays based the EHI generated during the delivery of LBB pacing therapy at the determined LBB pacing location using the plurality of different AV delays.
