![]() The time to the correct diagnosis was also shorter with RM (136 seconds vs. Blinded assessors (n = 11) reached the correct diagnosis using RM in 35/44 (80%) compared to 22/44 (50%) using CARTO-XP (P = 0.029). These assessors were allowed to annotate the CARTO-XP maps, but were blinded to conventional EP data.ĬARTO-XP maps of AT (10 patients) were studied in RM format and the diagnosis was confirmed by entrainment in all cases and with termination of tachycardia in 9/10 cases. ![]() Paired unannotated CARTO-XP and Ripple Maps were presented to experienced CARTO users with limited RM training. We hypothesized that RM would be superior to established 3D activation mapping.ĬARTO-XP™ maps of ATs were collected without any manual annotation and studied on a CARTO-based offline RM system. ![]() Ripple Mapping (RM) is a technique that displays electrogram time-voltage data simultaneously as dynamic bars on the surface shell to overcome these limitations. Three-dimensional (3D) mapping is often used to guide ablation in atrial tachycardia (AT), but maps can be susceptible to annotation and interpolation errors. ![]()
