AERP indicates atrial effective refractory period; BCL, basic drive cycle length; DCS, distal coronary sinus; HRA, high right atrium; LA, left atrium; LRA, low right atrium; MLRA, midlateral right atrial wall; PAF, paroxysmal atrial fibrillation; PCS, proximal coronary sinus; peAF, persistent atrial fibrillation; PV, pulmonary vein; RA, right atrium; and RAS, right atrial septum.
