摘要
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.
