Significance of electrical activity in the right superior pulmonary vein post-isolation and relationship to superior vena cava potentials

ConclusionsPersistent RSPV potentials occur rarely post-PVI despite the close proximity to electrically active SVC. When present, true PVP can be differentiated from FFP by low-amplitude pacing from SVC. Bipolar EGM morphology and high-amplitude pacing are unreliable at differentiating these potentials.
