Persistent SVC isolation with RSPV isolation. (A) Sustained SVC
fibrillation was confirmed irrespective of sinus rhythm in other
electrocardiograms (lead II, the RA and CS). (B) Voltage
mapping of the SVC, RA and LA. Low voltage area around the SVC was
consistent with that around the RSPV. CRA: cranial, CS: coronary sinus,
LA: left atrium, RA: right atrium, RAO: right anterior oblique, LAO:
left anterior oblique, LIPV: left inferior pulmonary vein, LSPV: left
superior pulmonary vein, RIPV: right inferior pulmonary vein, RSPV:
right superior pulmonary vein, SVC: superior vena cava.
