of cPVB/patient 1.2 PV potential location RSPV 9 (33%) RIPV 3 (11%) LSPV 10 (37%) LIPV 5 (19%) Wide double PV potentials interval 136 [+ or -] 16ms Relation to PV firing 24 (89%) cPVB = concealed pulmonary vein bigeminy; PV = pulmonary vein; RSPV = right superior pulmonary vein; RIPV = right inferior pulmonary vein; LSPV = left superior pulmonary vein; LIPV = left inferior pulmonary vein.
Mapping and ablation were performed in 789 PVs (198 patients): 198 right superior PVs (RSPVs), 198 right inferior PVs (RIPVs), 5 right middle PVs (RMPVs), 190 left superior PVs (LSPVs), 190 left inferior PVs (LIPVs), and 8 left common trunks.
ERPD1 was calculated for RSPV, RIPV, RA, RAA, LSPV, LIPV, LA, and LAA.
The ERP and WOV were measured at LSPV, LIPV, LA, LAA, MSL, RSPV, RIPV, ARGPM, RA, and RAA at baseline levels and the end of every hour during the 3 hours pacing period.
In the control group, the ERP at RSPV, RIPV, RA, RAA, ARGPM, LSPV, LIPV, LA, LAA, and MSL was markedly shortened in the second and third hour (Figure 3).
