Why the study?
Differences in cardiac chamber spatial excursion during PVCs versus sinus rhythm shift 3D electroanatomic mapping registration, prompting a strategy to adjust for this displacement in real time.
Does real-time reregistration of 3D location during PVC mapping account for spatial displacement relative to sinus rhythm?
Population

Displacement between PVC and sinus rhythm sites warrants caution in 3D mapping; this case report leaves open the value of real-time reregistration.
Does real-time reregistration of 3D location during PVC mapping account for spatial displacement relative to sinus rhythm?
During 3D electroanatomic mapping, PVC locations are spatially displaced relative to sinus rhythm, requiring adjustment for accurate ablation delivery.
