Identification of implanted electrode location

A medical device system comprising:

• telemetry circuitry adapted to download data from an implanted medical device that comprises electrodes implanted in a patient's heart, wherein the downloaded data comprises a first data channel and a second data channel, wherein each data channel is associated with a particular electrode of the implanted electrodes, wherein each data channel comprises electrode data from the patient's heart sensed by the electrode associated with the data channel;
• a memory storing:
• a first expected deflection pattern over a single cardiac cycle corresponding to a first possible electrode placement location;

• processing circuitry configured to execute the algorithm comprising:
• identifying one or more measured deflections in the electrode data for each data channel over a single cardiac cycle;
