Pacing thresholds were assessed before, immediately after, and 3 months after ablation and standardized to a pulse width of 0.4\u2009ms using the Lapicque\u2013Weiss model. Marked acute threshold elevation was defined as an increase in pacing threshold of \u2265\u20091.0\u2009V immediately after ablation. The anatomical relationship between ablation sites and ventricular lead locations was assessed based on the American Heart Association 17\u2010segment model of the left ventricle and classified as corresponding when ablation involved the same or opposing ventricular region as the lead location, adjacent when ablation involved a directly adjacent region, and remote otherwise.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Marked acute pacing\u2010threshold elevation occurred in 5 of 79 right ventricular (RV) leads (6.3%) and 2 of 22 evaluable left ventricular (LV) leads (9.1%). For RV leads, marked threshold elevation occurred in 4 of 14 patients (28.6%) in the corresponding group, 1 of 19 (5.3%) in the adjacent group, and none of 46 (0%) in the remote group. When threshold change was analyzed as a continuous variable, the acute increase was significantly greater in the corresponding group (+\u20090.74\u2009V; 95%CI 0.465\u20131.018) than in the adjacent (+\u20090.31\u2009V; 95%CI 0.076\u20130.550) and remote (+\u20090.007\u2009V; 95%CI\u2009\u2212\u20090.145\u20130.160) groups. For LV leads, the pacing threshold increased significantly after ablation involving the corresponding segment (+\u20090.71\u2009V; 95%CI 0.167\u20131.245), although the overall association between anatomical relationship and threshold change was not significant. At 3 months, pacing thresholds in the corresponding groups were not significantly different from baseline for either RV or LV leads.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Marked acute pacing\u2010threshold elevation was observed in both RV and LV leads after ventricular arrhythmia ablation using a dual\u2010energy lattice\u2010tip catheter. However, both RV and LV thresholds were no longer significantly different from baseline at 3 months. These findings suggest the importance of considering the anatomical relationship between ablation sites and CIED leads and of careful peri\u2010procedural assessment of lead function during ventricular ablation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/jce.70528","type":"journal-article","created":{"date-parts":[[2026,10,11]],"date-time":"2026-10-11T16:42:03Z","timestamp":1791736923000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Changes in Lead Parameters of Cardiac Implantable Electronic Devices After VT\/VF Ablation Using a Dual\u2010Energy Lattice\u2010Tip Catheter"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7495-673X","authenticated-orcid":false,"given":"Kazuto","family":"Hayasaka","sequence":"first","affiliation":[{"name":"Department of Cardiology Institute for Clinical and Experimental Medicine Prague Czechia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5625-0071","authenticated-orcid":false,"given":"Petr","family":"Peichl","sequence":"additional","affiliation":[{"name":"Department of Cardiology Institute for Clinical and Experimental Medicine Prague Czechia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-8251-2001","authenticated-orcid":false,"given":"Nicoletta","family":"Ventrella","sequence":"additional","affiliation":[{"name":"Department of Cardiology Institute for Clinical and Experimental Medicine Prague Czechia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ibrahim","family":"Fahmawi","sequence":"additional","affiliation":[{"name":"Department of Cardiology Institute for Clinical and Experimental Medicine Prague Czechia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josef","family":"Marek","sequence":"additional","affiliation":[{"name":"Department of Cardiology Institute for Clinical and Experimental Medicine Prague Czechia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"\u0160tiavnick\u00fd","sequence":"additional","affiliation":[{"name":"Department of Cardiology Institute for Clinical and Experimental Medicine Prague Czechia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jana","family":"Ha\u0161kov\u00e1","sequence":"additional","affiliation":[{"name":"Department of Cardiology Institute for Clinical and Experimental Medicine Prague Czechia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1487-5823","authenticated-orcid":false,"given":"Predrag","family":"Stojadinovi\u0107","sequence":"additional","affiliation":[{"name":"Department of Cardiology Institute for Clinical and Experimental Medicine Prague Czechia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0448-5143","authenticated-orcid":false,"given":"Dan","family":"Wichterle","sequence":"additional","affiliation":[{"name":"Department of Cardiology Institute for Clinical and Experimental Medicine Prague Czechia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josef","family":"Kautzner","sequence":"additional","affiliation":[{"name":"Department of Cardiology Institute for Clinical and Experimental Medicine Prague Czechia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,11]]},"reference":[{"issue":"18","key":"e_1_2_9_2_1","doi-asserted-by":"crossref","first-page":"1660","DOI":"10.1056\/NEJMoa2307291","article-title":"Pulsed Field or Conventional Thermal Ablation for Paroxysmal Atrial Fibrillation","volume":"389","author":"Reddy V.
