1. A system for assisting in noninvasive location selection for an implantable electrode comprising:
electrode apparatus comprising a plurality of external electrodes configured to be located proximate tissue of a patient; imaging apparatus configured to image at least a portion of blood vessel anatomy of the patient's heart; a display apparatus comprising a graphical user interface, wherein the graphical user interface is configured to depict the at least a portion of blood vessel anatomy of the patient's heart for implantation of an implantable electrode; and computing apparatus coupled to the electrode apparatus, imaging apparatus, and display apparatus and configured to assist a user in noninvasively selecting a location for the implantable electrode, wherein the computing apparatus is further configured to:
measure mechanical motion of a plurality of implantation site regions of the at least a portion of blood vessel anatomy of the patient's heart using the imaging apparatus, wherein each region of the plurality of implantation site regions is different from the other regions of the plurality of implantation site regions,measure surrogate electrical activation time of the plurality of implantation site regions of the patient's heart using the plurality of external electrodes of the electrode apparatus, wherein the surrogate electrical activation time for each region of the plurality of implantation site regions is measured using one or more external electrodes,determine one or more candidate site regions of the plurality of implantation site regions of the at least a portion of blood vessel anatomy of the patient's heart for implantation of the implantable electrode based on the measured mechanical motion and measured electrical activation time of the plurality of regions, wherein the one or more candidate site regions comprise mechanical motion contraction times greater than or equal to a mechanical motion threshold based on the latest mechanical motion contraction time of the plurality of implantation site regions and electrical activation times greater than or equal to an electrical activation threshold based on the latest electrical activation time of the plurality of implantation site regions, andidentify, on the graphical user interface, the one or more candidate site regions for implantation of the implantable electrode.
