We divided the study patients into two groups: the patients underwent RF ablation using the CARTO 3 version 7 with LAT-hybrid\u2122 module (hybrid group) and the other patients using the CARTO 3 version 6 without LAT-hybrid\u2122 module (conventional group).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The primary results of this study demonstrate that the mean hybrid distance is 4.03\u2009\u00b1\u20092.33 mm, and this automated algorithm can correct for the positional shift with accuracy comparable to manual correction.
