EDEL was detected in 11 patients (10 RFA and one CBA). In the RFA group, the highest LET recorded was similar between patients with and without EDEL (40.6 [40.1\u201341]\u00b0C vs. 40.2 [39.1\u201340.9]\u00b0C; <jats:italic>p<\/jats:italic>\u2009=\u2009.313), however, the rate of LET rise for the highest recorded peak was higher (0.08 [0.03\u20130.12]\u00b0C\/s vs. 0.02 [0.01\u20130.05]\u00b0C\/s; <jats:italic>p<\/jats:italic>\u2009=\u2009.033), and the area under the curve (AUC) for the highest peak was smaller (412.5 [206.8\u2013634.1] vs. 588.6 [380.4\u2013861.1]; <jats:italic>p<\/jats:italic>\u2009=\u2009.047) in patients who had EDEL. In case of CBA, the patient with EDEL had a faster LET decline (0.12 vs. 0.07 [0.02\u20130.14]\u00b0C\/s), and a smaller AUC for the lowest trough (2491.3 vs. 2629.3 [1712.6\u20135283.2]).
