Abstract
Systems, methods, and interfaces are described herein for assisting in noninvasive location selection for an implantable electrode for use in cardiac therapy. Mechanical motion information and surrogate electrical activation times may be used to identify one or more candidate site regions.
Claims25
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;
- and
- computing apparatus coupled to the electrode apparatus, imaging apparatus, and display apparatus and configured to provide the graphical user interface displayed on the display apparatus to assist a user in noninvasively selecting a location for an implantable electrode, wherein the computing apparatus is further configured to:
- display, on the graphical user interface, at least a portion of blood vessel anatomy of the patient's heart,
- measure mechanical motion of the at least a portion of blood vessel anatomy of the patient's heart using the imaging apparatus,
- display, on the graphical user interface, mechanical motion information of one or more regions of the at least a portion of blood vessel anatomy of the patient's heart based on the measured mechanical motion,
- identify a region of the one or more regions of the at least a portion of blood vessel anatomy of the patient's heart,
- measure surrogate electrical activation time using one or more external electrodes of the plurality of external electrodes of the electrode apparatus proximate the identified region of the at least a portion of blood vessel anatomy of the patient's heart, and
- display, on the graphical user interface, the measured surrogate activation time for the identified region of the at least a portion of blood vessel anatomy of the patient's heart.
