Abstract: A catheter system includes a catheter comprising a tip assembly, the tip assembly having a plurality of electrodes and the plurality of electrodes are configured to measure electrical signals. The system also includes a processing unit configured to: receive a first electrical signal sensed by a first electrode of the plurality of electrodes and a second electrical signal sensed by a second electrode of the plurality of electrodes. A first vector is determined based on the first electrical signal that corresponds to the first electrode. A second vector is determined based on the second electrical signal that corresponds to the second electrode. A resultant vector is determined by summing at least the first vector and the second vector, wherein the resultant vector is indicative of the orientation of the tip assembly.

Abstract: Methods and systems for mapping and displaying cardiac structures are disclosed. The method includes sensing cardiac electrical signals at a plurality of points and generating a cardiac map of at least a portion of one or more cardiac structures based on at least a portion of the sensed cardiac electrical signals. A surface map having a corresponding first position relative to the cardiac map is generated. The surface map includes a first surface point, where a first cardiac electrical signal feature is represented on the surface map at the first surface point if a corresponding first cardiac electrical signal is sensed at a point that is located within a threshold distance of the first surface point. The cardiac map and the surface map, at the first position, are displayed. The surface map may be repositioned to a second position.
