Abstract
A method for use with an implantable system including a lead having multiple electrodes implantable proximate to a patient's left ventricular (LV) chamber includes simultaneously delivering pacing pulses over corresponding pacing vectors defined by electrodes proximate to the LV chamber. The method includes recording evoked responses responsive to the pacing pulses that are measured over separate corresponding sensing channels. The method also includes comparing the evoked responses to a template that represents local capture of a local LV tissue region along one or more of the corresponding pacing vectors. The comparison is used to determine whether the pacing pulses achieved local capture along the corresponding pacing vectors. At least one of the pacing pulses or pacing vectors are updated based on the comparison of the evoked responses to the template in order to determine a local capture threshold for the corresponding pacing vectors.
