1. A system, comprising:
at least one of a guidewire or catheter with a distal end configured to be located within a chamber of a heart proximate to a sight of interest (SOI) at a septal wall;
a lead having a proximal end and a distal end, the lead configured to be advanced along at least one of the guidewire or the catheter to the SOI;
one or more electrodes located at a distal end of at least one of the catheter, guidewire or lead, at least a first electrode from the one or more electrodes configured to be inserted to different depths into the septal wall at the SOI;
a pulse generator configured to generate stimulation energy; and
one or more processors that, when executing program instructions, are configured to electrically map a target depth within the septal wall by at least one of:
directing the pulse generator to deliver stimulation energy to the first electrode, as pacing pulses, when the first electrode is inserted to the corresponding different depths within the septal wall; or
sensing evoked responses at the corresponding different depths within the septal wall when the first electrode is inserted to the corresponding different depths within the septal wall.
