Examples of reentry and focal source localization. a Final ASAP map obtained using a Lasso catheter with a reentry source (simulation case of Fig. 1a). b Final AF source area probability (ASAP) map obtained using a spiral catheter with a focal source (simulation case of Fig. 1b). The black dotted boundary indicates the high-probability (HP) area in both cases. The black tracings indicate the trajectory of the source core
