Results
23 patients were included. Percentage of points with voltage lower than
0.5mV and 0.3 mV was significantly higher in maps in AF compared to maps
in SR: 38.2% of points <0.5mV in AF vs. 22.9% of points
<0.5mV in SR (p<0.001); 22.3% of points
<0.3mV in AF vs. 14% of points <0.3mV in SR
(p<0.001). Areas with reduced voltage were significantly
bigger in maps in AF (0.5mV threshold, mean area in AF
41.3cm2 ± 42.5cm2 vs
11.7cm2 ±17.9cm2 in SR, p
<0.001; 0.3mV threshold, mean area in AF
15.6cm2 ±22.1cm2 vs
6.2cm2 ±11.5cm2 in SR, p
<0.001).
