Atrial mapping during pulmonary vein pacing to detect conduction gaps in a second pulmonary vein isolation procedure

摘要

Background Finding the conduction gaps in redo PV isolation procedures is challenging, and several maneuvers have been described. In the present study, we analyze the pace and map (P&M) maneuver [atrial mapping during pulmonary vein (PV) pacing] to locate the gaps in redo PV isolation procedures.
