Fig. 5

AF source area probability (ASAP) mapping constructed for three subjects. The figures show the posterior view of the left atrium, and the black circles indicate the possible location of reentries as manually labeled by an electrophysiologist according to the criteria in [25]. LPVs: left pulmonary veins. RPVs: right pulmonary veins. The electrogram recordings at catheter placement L1 is shown in Additional file 4: Figure S4
