Distances to EP_var sites are only provided for emergent RDs that did not correspond to an RD observed in the same location in pre-ablation simulations under EP_var conditions, as described by Deng et al.¹⁴

EP_avg, average AF electrophysiology; EP_var, variable electrophysiology; IVC, inferior vena cava; LA, left atrium; LIPV, left inferior pulmonary vein; LSPV, left superior pulmonary vein; RA, right atrium; RAA, right atrial appendage; RD, re-entrant driver; RIPV, right inferior pulmonary vein; RSPV, right superior pulmonary vein; SVC superior vena cava.

^aRDs for which activation maps are shown in Figure 4.

^bEmergent RDs that were completely distinct from any RDs observed in any pre-ablation simulations, regardless of whether they were conducted under either EP_avg or EP_var conditions.
