Distribution of focal (F) and rotational (R) activities of long-standing persistent atrial fibrillation in group 1. The left atrium was divided into 11 regions: right superior pulmonary vein (RSPV), right inferior pulmonary vein (RIPV), left superior pulmonary vein (LSPV), left inferior pulmonary vein (LIPV), left atrial appendage (LAA), septum, anterior wall, roof, posterior wall, bottom, and lateral wall. The number and percentage of patients in group 1 with CARTOFINDER-identified focal/rotational activities in each region were calculated. For example, in group 1, 32 patients (80%) had focal activities and 2 patients (5%) had rotational activities in the LAA.
