SPATIAL DISPLACEMENT OF THREE DIMENSIONAL ELECTROANATOMIC MAPPING POINTS DURING PREMATURE VENTRICULAR COMPLEXES VERSUS SINUS RHYTHM

Point-by-point 3D electroanatomic mapping is used to guide catheter ablation of PVCs. Due to differences in the spatial excursion of the cardiac chambers during cardiac cycles in PVCs versus sinus rhythm, 3D location registration during PVCs may be shifted relative to sinus rhythm. In this study, we
