*Defined fragmented spectral potentials near the left inferior pulmonary vein insertion and the lateral wall of the right atrium and crista terminalis. However, these areas were not defined as GPs. ^†An A–H prolongation during ablation was seen in the anterior aspect of the mitral valve annulusi 6% of patients. CS = coronary sinus; EGM = electrogram; GP = ganglionated plexi; HFS = high-frequency stimulation; IAS = interatrial septum; LAA = left atrial appendage; LIGP = left inferior ganglionated plexi; LIPV = left inferior pulmonary vein; IVC-CS = inferior vena cava-coronary sinus junction; LoM = the ligament of Marshall; LSGP = superior left atrial GP; LSPV = left superior pulmonary vein; MTGP = Marshall tract ganglionated plexi; N/D = not defined; PMLGP = posteromedial left atrial GP; RA = right atrium; RIGP = inferior right atrial GP; RSGP = superior right atrial GP; SA = spectral analysis; SVC = superior vena cava.
