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).
