Figure 1: Reconstituted curves from VISITAG™ Module data export demonstrating first-annotated site “end” time-point (i.e. site 1-to-2 transition) at the first 0g CF event, 15.5s (ACCURESP™ “on”) and 15.6s (ACCURESP™ “off”) following RF onset in case 5, right PV. This small difference in the annotated RF duration between ACCURESP™ settings results in a single vertical red line representing ACURESP™ “on” and “off” annotation timing. Catheter tip position shift, (position) standard deviation (SD), CF and impedance are plotted separately; x-axis displays the PIU time stamp (i.e. running case time, shown in thousands of seconds) and vertical dashed lines indicate end-expiration time-points. The force-over-time 100% minimum 1g CF filter ensures that automated RF annotation only occurs when CF is continuously maintained ≥1g, indicated by black curves; pink position shift, SD and impedance curves indicate <100% CF filter preference attainment. The SD curve returns to black at 1s (or 60 sites) following attainment of both CF and position stability within the chosen VISITAG™ Module filter preferences, in view of the CARTO®3 SD calculation “system logic”. Note: “Session 200 at sites 41 and 42” represents the unique automatically generated VISITAG™ Module annotated identifiers for this site.
Figure 2: Reconstituted curves from VISITAG™ Module data export demonstrating first-annotated site “end” time-point (i.e. site 1-to-2 transition) at 15.2s (ACCURESP™ “off”, blue line) and 26.5s (ACCURESP™ “on”, red line) following RF onset in case 5, left PV. Transition to site-2 with ACCURESP “off” coincided with UE morphology change from pure R at site-1 completion, to RS at site-2 onset (ACCURESP™ “off” ITD 4.1mm); clear changes in the catheter tip position shift, (position) standard deviation (SD) and CF coincide with ACCURESP™ “off” annotation. All curves are drawn black, since CF was maintained ≥1g and the catheter movement was sufficiently rapid to ensure that all catheter tip location data was annotated to either site-1, or 2 (ACCURESP™ “off”). Note: “Session 181 at sites 1 and 2” represents the unique automatically generated VISITAG™ Module annotated identifiers for this site.
Figure 3: ACCURESP™ RMA “on” minus “off” difference in annotated RF duration, FTI and impedance drop according to site 1-to-2 ITD with ACCURESP™ “off”. Data are shown for all 13 LAPW inter-ablation site transitions achieved during constant catheter-tissue contact, with corresponding correlation data.
