Fractionation mapping. Electroanatomical model showing fractionation map (light gray) and atrial walls (purple). Yellow dotted ellipses show ganglia GP1 to GP4. T2 to T4 indicate the fractionation map sensitivity and specificity threshold: the higher the number is, the more specific and less sensitive it is. This parameter must be adjusted by the operator to get the best view of the ganglionated plexus areas. Usually, the P point needs the highest threshold and GP1 the lowest. The software developed by Pachon and St Jude Medical (now Abbott Laboratories). IVC = inferior vena cava; LA = left atrium; LIPV = left inferior pulmonary vein; LSPV = left superior pulmonary vein; RA = right atrium; RIPV = right inferior pulmonary vein; RSPV = right superior pulmonary vein; SVC = superior vena cava.
