The electrophysiologic data were compared between the patients in the para\u2010Hisian group and those with VAs arising from the right ventricular (RV) outflow tract (RVOT group). The distal bipolar electrogram at the successful ablation sites in the para\u2010Hisian group exhibited a significantly greater R\u2010wave duration, lower R\u2010wave amplitude, and slower upright deflection of the initial R wave than did those in the RVOT group (all P &lt; 0.001). In the para\u2010Hisian group, a total of 56 radiofrequency (RF) energy applications were delivered, of which the local electrograms at 16 successful and 40 unsuccessful ablation sites were reviewed. High\u2010frequency R\u2010wave potentials of the bipolar electrogram were present in 14 (88%) of the successful ablation sites. An R\u2010wave duration of greater than 34 ms had a discriminatory power for indicating the site of a successful ablation (area under the receiver\u2013operator characteristics curve 0.90, sensitivity 94%, specificity 80%).<\/jats:p><jats:p> <jats:italic>Conclusions:<\/jats:italic> The successful ablation site of the para\u2010Hisian VAs had distinctive local electrogram characteristics. A longer R\u2010wave duration of the bipolar electrogram with high\u2010frequency potentials could be a novel predictor of a successful ablation. <jats:italic>(J Cardiovasc Electrophysiol, Vol. 22, pp. 878\u2010885, August 2011)<\/jats:italic><\/jats:p>","DOI":"10.1111\/j.1540-8167.2011.02014.x","type":"journal-article","created":{"date-parts":[[2011,2,18]],"date-time":"2011-02-18T21:44:46Z","timestamp":1298065486000},"page":"878-885","source":"Crossref","is-referenced-by-count":27,"title":["Catheter Ablation of Ventricular Arrhythmias Arising from the Right Ventricular Septum Close to the His Bundle: Features of the Local Electrogram at the Optimal Ablation Site"],"prefix":"10.1111","volume":"22","author":[{"given":"YUKI","family":"KOMATSU","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"KIYOSHI","family":"OTOMO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"HIROSHI","family":"TANIGUCHI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"KEN","family":"KAKITA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"KEI","family":"TAKAYAMA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"HIDEOMI","family":"FUJIWARA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"YOSHITO","family":"IESAKA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2011,2,18]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.68.5.917"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.82.6.2093"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.85.5.1666"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(94)90375-1"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.1995.tb06970.x"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(97)00004-1"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1540-8167.2001.00536.x"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2006.00519.x"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2006.00577.x"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2005.40787.x"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2007.09.029"},{"key":"e_1_2_6_13_2","first-page":"132","article-title":"Radiofrequency catheter ablation of idiopathic right ventricular tachycardia near the His bundle","volume":"90","author":"Shimoike E","year":"1999","journal-title":"Fukuoka Igaku Zasshi"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2006.09.025"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.1997.tb00619.x"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2005.50155.x"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1460-9592.2001.00441.x"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(95)00287-7"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2004.02.020"}],"container-title":["Journal of Cardiovascular Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1540-8167.2011.02014.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.1540-8167.2011.02014.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,15]],"date-time":"2023-10-15T02:57:39Z","timestamp":1697338659000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1540-8167.2011.02014.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,2,18]]},"references-count":18,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2011,8]]}},"alternative-id":["10.1111\/j.1540-8167.2011.02014.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1540-8167.2011.02014.x","archive":["Portico"],"relation":{},"ISSN":["1045-3873","1540-8167"],"issn-type":[{"value":"1045-3873","type":"print"},{"value":"1540-8167","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,2,18]]}}}
