The purpose of the study was to investigate the success and complication rate particularly regarding the induction of an atrioventricular (AV) block by radiofrequency (RF) ablation in elderly patients with and without a preexisting AV block.<\/jats:p><jats:p> <jats:italic>Methods and Results:<\/jats:italic> Between February 1998 and July 2004, all patients with symptomatic AVNRT referred for slow\u2010pathway ablation in our institution were included and divided into two groups: group 1 patients younger than 75 years (n = 508) and group 2 patients \u226575 years (n = 70).<\/jats:p><jats:p>A preexisting prolonged PR interval was present in 17 (3.3%) patients of group 1 and in 26 (37%, P &lt; 0.0001) patients of group 2. Following successful slow\u2010pathway ablation (follow\u2010up time group 1: 37 \u00b1 22, group 2: 37 \u00b1 24 months) no induction of an AV block was observed in group 2 but in four patients of group 1 (0.79%) a complete heart block was induced requiring a pacemaker implantation. In group 1, 15 (2.95%) patients with a recurrence of AVNRT were readmitted for a repeat ablation procedure. No recurrences occurred in group 2.<\/jats:p><jats:p> <jats:italic>Conclusion:<\/jats:italic> Despite a higher incidence of preexisting prolonged PR intervals slow\u2010pathway ablation in elderly patients is both effective and safe and should be considered as the first line therapy also in this patient population<\/jats:p>","DOI":"10.1111\/j.1540-8167.2005.40717.x","type":"journal-article","created":{"date-parts":[[2005,6,9]],"date-time":"2005-06-09T08:46:42Z","timestamp":1118306802000},"page":"608-610","source":"Crossref","is-referenced-by-count":53,"title":["Efficacy and Safety of Radiofrequency Catheter Ablation of Atrioventricular Nodal Reentrant Tachycardia in the Elderly"],"prefix":"10.1111","volume":"16","author":[{"given":"THOMAS","family":"ROSTOCK","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"TIM","family":"RISIUS","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"RODOLFO","family":"VENTURA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"HANNO U.","family":"KLEMM","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CHRISTIAN","family":"WEISS","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ANNA","family":"KEITEL","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"THOMAS","family":"MEINERTZ","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"STEPHAN","family":"WILLEMS","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,4,28]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.85.6.2162"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199207303270504"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.eurheartj.a015006"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(99)00544-6"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(98)00289-6"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1053\/euhj.2000.2182"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ehj.2004.05.017"},{"key":"e_1_2_6_9_2","first-page":"504","volume-title":"Cardiac Electrophysiology: From Cell to Bedside","author":"Otomo K","year":"1999"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1053\/euhj.2000.2124"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.2000.tb00891.x"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1097\/00019501-199809060-00007"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000091380.04100.84"}],"container-title":["Journal of Cardiovascular Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1540-8167.2005.40717.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.1540-8167.2005.40717.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,11]],"date-time":"2023-10-11T03:36:23Z","timestamp":1696995383000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1540-8167.2005.40717.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2005,4,28]]},"references-count":12,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2005,6]]}},"alternative-id":["10.1111\/j.1540-8167.2005.40717.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1540-8167.2005.40717.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":[[2005,4,28]]}}}
