Existing CHB animal models are limited by surgical recovery time and reliance on intrinsic escape rhythms. We describe a novel closed-chest rabbit model of CHB involving transcatheter radiofrequency (RF) atrioventricular (AV) node ablation and ventricular rate control with chronic transvenous pacing. Permanent CHB was achieved in 34 of 38 attempts overall. Procedural mortality due to cardiac tamponade ( n = 2), airway complications ( n = 2), and unknown causes ( n = 5) occurred in nine animals. Survivors with CHB ( n = 28) were maintained for \u226422 days, during which there were three late deaths related to infection ( n = 1) or respiratory distress ( n = 2). None of the survivors with CHB showed recovery of AV conduction or pacemaker capture loss during chronic ventricular pacing at about one-half normal sinus rates, and 25 animals surviving to death showed no overt signs of hemodynamic compromise such as lethargy, poor feeding, or respiratory distress. This approach provides a reproducible nonsurgical CHB model with adjustable ventricular rate control. <\/jats:p>","DOI":"10.1152\/japplphysiol.00714.2001","type":"journal-article","created":{"date-parts":[[2015,3,3]],"date-time":"2015-03-03T20:40:04Z","timestamp":1425415204000},"page":"1199-1204","source":"Crossref","is-referenced-by-count":12,"title":["A novel rabbit model of variably compensated  complete heart block"],"prefix":"10.1152","volume":"92","author":[{"given":"Fumiaki","family":"Suto","sequence":"first","affiliation":[{"name":"Cardiovascular Research Programme, Hospital for Sick Children Research Institute;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sean A.","family":"Cahill","sequence":"additional","affiliation":[{"name":"Cardiovascular Research Programme, Hospital for Sick Children Research Institute;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gregory J.","family":"Wilson","sequence":"additional","affiliation":[{"name":"Cardiovascular Research Programme, Hospital for Sick Children Research Institute;"},{"name":"Pathology Division and"},{"name":"Department of Laboratory Medicine and Pathobiology, University of Toronto; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert M.","family":"Hamilton","sequence":"additional","affiliation":[{"name":"Cardiovascular Research Programme, Hospital for Sick Children Research Institute;"},{"name":"Cardiology Division, Hospital for Sick Children;"},{"name":"Department of Pediatrics, University of Toronto, Toronto, Ontario, Canada M5G 1X8"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ilana","family":"Greenwald","sequence":"additional","affiliation":[{"name":"Cardiovascular Research Programme, Hospital for Sick Children Research Institute;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gil J.","family":"Gross","sequence":"additional","affiliation":[{"name":"Cardiovascular Research Programme, Hospital for Sick Children Research Institute;"},{"name":"Cardiology Division, Hospital for Sick Children;"},{"name":"Department of Pediatrics, University of Toronto, Toronto, Ontario, Canada M5G 1X8"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"24","reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.81.2.401"},{"key":"B2","first-page":"181","volume":"20","author":"Bonatti V","year":"1998","journal-title":"Pediatr Med Chir"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM197712012972203"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1016\/0002-8703(93)90752-U"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1152\/jappl.1998.85.2.758"},{"key":"B7","first-page":"211","volume":"51","author":"O'Connor JM.","year":"1947","journal-title":"Proc R Irish Acad"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1152\/jappl.1968.25.5.631"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.98.11.1136"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.100.24.2455"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.98.11.1125"},{"key":"B12","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.91.3.864"}],"container-title":["Journal of Applied Physiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.physiology.org\/doi\/pdf\/10.1152\/japplphysiol.00714.2001","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,9,8]],"date-time":"2019-09-08T19:19:16Z","timestamp":1567970356000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.physiology.org\/doi\/10.1152\/japplphysiol.00714.2001"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2002,3,1]]},"references-count":11,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2002,3,1]]}},"alternative-id":["10.1152\/japplphysiol.00714.2001"],"URL":"https:\/\/doi.org\/10.1152\/japplphysiol.00714.2001","relation":{},"ISSN":["8750-7587","1522-1601"],"issn-type":[{"value":"8750-7587","type":"print"},{"value":"1522-1601","type":"electronic"}],"subject":[],"published":{"date-parts":[[2002,3,1]]}}}
