1. A method for displaying a three dimensional visualization of cardiac motion, the method comprising:
- obtaining point specific (PS) motion data for a plurality of map points, wherein the PS motion data indicates an amount of motion that occurred at the corresponding map point on a wall of the heart during at least one cardiac cycle;
determining three dimensional (3D) positions of the map points during the cardiac cycle based on the PS motion data;
selecting sets of 3D positions for corresponding frames of the cardiac cycle; and
generating 3D visualizations for the selected sets of 3D positions, wherein the 3D visualizations illustrate trajectory loops for the map points over at least a portion of the cardiac cycle.

Abstract
A method and system for displaying a three dimensional visualization of cardiac motion. The method and system obtain point specific (PS) motion data for a plurality of map points. The PS motion data indicates an amount of motion that occurred at the corresponding map point on a wall of the heart during at least one cardiac cycle. The method and system determine three dimensional (3D) positions of the map points during the cardiac cycle based on the PS motion data and select a set of 3D positions based on a frame rate. The method and system further generate 3D visualizations for each selected set of 3D positions.
