3.3 Relationship between the CFAE areas and AF rotors
Figure 6 shows the proportion of CFAE areas between the NPAs and PAs. Fifteen (25%) of 60 NPAs overlapped with CFAE areas, while 49 (21%) of 227 PAs also overlapped with CFAE areas. The proportion of CFAE areas did not differ between teh NPAs and PAs (p = 0.441). A representative case showed that a CFAE area could be found on the LA septum where no NPAs could found (Figure 5).
