Dominant Activation Pattern During Each 10-s Segment of AF Over the 10-min Recording for Each Mapped Region
A single dominant pattern recurs during every 10-s atrial fibrillation (AF) segment (1-6) in 8 of 13 mapped regions (red). In 3 further mapped regions a single dominant pattern is seen to recur in 5 of the 6 segments (green) and in 1 region a single dominant pattern recurs in 4 of the 6 segments (blue).
