Electric field tomography
First Claim
1. A method for evaluating movement of a tissue location in a subject, said method comprising:
- (a) generating a continuous electric field so that said tissue location is present in said continuous field; and
(b) detecting a change in property of the continuous electric field at said tissue location to evaluate movement of said tissue location.

Abstract
Methods for evaluating motion of a tissue, such as of a cardiac location, e.g., heart wall, via continuous field tomography are provided. In the subject methods, a continuous field (e.g., an electrical, mechanical, electromechanical, or other field) sensing element is stably associated with the tissue location. A property of the applied continuous field is detected with the sensing element to evaluate movement of the tissue location. Also provided are systems, devices and related compositions for practicing the subject methods. The subject methods and devices find use in a variety of different applications, including cardiac resynchronization therapy.
