The LI drop was significantly greater and faster than the GI drop in all segments. The 90% decay time of LI was consistently 5\u20136\u2009s, suggesting effective lesion formation during the resistive heating phase. LI provides a more reliable and localized indicator of tissue response than GI. The temporal profile of LI supports its utility in guiding safe and effective lesion delivery, particularly in the thin myocardial tissue of the SVC.<\/jats:p>\n                  <\/jats:sec>\n
