1. A method to analyze data of a region of interest in order to generate a cardiac map, the method comprising:
- utilizing one or more processors;
acquiring data recordings of motion data at each of a select number of map points for the region of interest with a navigation system motion sensor in contact with the region of interest;
determining cycle lengths associated with cardiac events in the data recordings, wherein the determining operation includes determining a plurality of cycle lengths in connection with a first map point of the select number of map points;
equalizing cycle lengths among different map points for the region of interest;
modifying the motion data based on the equalizing operation; and
displaying the modified motion data on a display.

Abstract
A method and system are provided for equalizing cycle lengths among different map points during mapping studies. Different embodiments may be applicable to different circumstances and physiological settings. A compression embodiment encapsulates the entire behavior of a map point throughout its native cycle length. A truncation and rotation embodiment, and an extension and rotation embodiment allow for a more physiologically-relevant processing of the motion data.
