Figure 4: Average temporal fluctuation in catheter angle of incidence (degrees/s) in the lateral and axial planes for each ablation lesion, stratified according to CTI anatomical site and the use of a long sheath. Significant p values highlighted; other relationships non-significant.
As these findings inferred that the use of a long sheath attenuated the catheter tip instability seen at the Mid CTI, the relationship between AI and ID was re-examined according to sheath use (table 4).
