Values are mean ± SD.

Ant = anterior wall; CL = cycle length; LA = left atrium; LAA = left atrial appendage; Lat = lateral wall; LI = left inferior; LS = left superior; Post = posterior wall; PV = pulmonary vein; RA = right atrium; RI = right inferior; RS = right superior; SCV = superior caval vein; Sept = septum.

  • p < 0.01 compared with all other RA regions.
