Qualitative index of assessment of fibrosis
For the 0.5mV threshold, 91% of patients obtained a score equal to or
greater than 5 points which, considering the description of our index,
means that LVA in SR were present as LVA in maps in AF. The remaining
9% did not have LVA in SR maps, so location comparison could not be
made. For the 0.3mV threshold, 52% of patients obtained a score equal
to or greater than 5 points which, considering our index, means that LVA
in SR were present in AF. In 39% of patients, there were no LVA in maps
in SR, so location comparison could not be made. Finally, in the
remaining 9% of patients, the score was less than 4 points, so LVA in
SR were not represented as LVA in AF.
