Abstract:
1. A system for mapping endocardial tissue, said system, comprising: a catheter having a catheter distal end for insertion into a patient; a plurality of sensors associated with said distal end, wherein said plurality of sensors are configured to obtain measurements of electrical potential of endocardial tissue in contact with said sensors such that current flow in each sensor is proportional to said electrical potential of said endocardial tissue, wherein each of the plurality of sensors comprise: a computer accessible memory that stores said measurements of said electrical potential of said endocardial tissue obtained by said plurality of sensors over a time duration; and one or more computer processors that correlate said measurements of said electrical potential of said endocardial tissue with a location of said distal end of said catheter to create an endocardial map of said tissue.
