Method and system for implanting a septal wall electrode

A system, comprising:

• a first electrode configured to be located within a septal wall;
• a second electrode configured to be located outside of the septal wall;
• wherein the first electrode and the second electrode are configured to measure the impedance data,
• an impedance circuit configured to measure impedance along an impedance monitoring (IM) vector between the first and second electrodes;
• a memory configured to store program instructions;
• one or more processors that, when executing the program instructions, are configured to:
• obtain impedance data indicative of an impedance along the IM vector with the first electrode located at different depths within the septal wall as the first electrode advances through the septal wall, the impedance data including a set of data values associated with the different depths of the first electrode within the septal wall as the first electrode advances through the septal wall;
• determine when the first electrode is located at a target depth within the septal wall based on the impedance data;
• and
• communicate the target depth for the first electrode based the impedance data measured by the first electrode and the second electrode.
