Claim 0:
1. A system for generating an animated map of a cardiac activation wavefront, comprising a computer configured to:
receive a plurality of data points, wherein each data point of the plurality of data points comprises location information and activation timing information;
display a model of a portion of a cardiac surface; and
sequentially display, on the model of the portion of the cardiac surface, a plurality of time markers corresponding to the plurality of data points over a playback time period,
wherein, for each time marker of the plurality of time markers:
a time marker display location on the model of the portion of the cardiac surface is determined by the location information for a respective data point of the plurality of data points,
a time marker display sequence over the playback time period is determined by the activation timing information for the respective data point of the plurality of data points, and
a time marker visibility is determined by a distance between the respective data point of the plurality of data points and a position of the cardiac activation wavefront at a point in time during the playback time period, such that the time marker for the respective data point of the plurality of data points is visible only when the cardiac activation wavefront is within a preset distance of the respective data point of the plurality of data points at the point in time during the playback time period.
