The His bundle electrograms obtained during sinus rhythm demonstrated a normal A-H (atrium-to-His bundle) time in one patient and a low normal A-H time in two patients. The H-V (His bundle-to-ventricle) time was short in all three patients. Atrial pacing in two patients produced an attenuated degree of prolongation of the A-H time without a change in conduction distal to the proximal His bundle. The probable mechanisms of accelerated conduction in these three patients include: (1) partial A-V nodal bypass via (a) the posterior intenodal tract or (b) functional bypass fibers within the A-V node; and (2) accelerated conduction within the A-V conduction system distal to the A-V node.<\/jats:p>","DOI":"10.1161\/01.cir.44.4.696","type":"journal-article","created":{"date-parts":[[2012,6,11]],"date-time":"2012-06-11T23:56:43Z","timestamp":1339459003000},"page":"696-708","update-policy":"http:\/\/dx.doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":35,"title":["Lown-Ganong-Levine Syndrome"],"prefix":"10.1161","volume":"44","author":[{"given":"WILLIAM J.","family":"MANDEL","sequence":"first","affiliation":[{"name":"From the Department of Cardiology, Cedars-Sinai Medical Center and the Department of Medicine, University of California at Los Angeles, California."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"RONALD","family":"DANZIG","sequence":"additional","affiliation":[{"name":"From the Department of Cardiology, Cedars-Sinai Medical Center and the Department of Medicine, University of California at Los Angeles, California."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"HAYAKAWA","sequence":"additional","affiliation":[{"name":"From the Department of Cardiology, Cedars-Sinai Medical Center and the Department of Medicine, University of California at Los Angeles, California."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","container-title":["Circulation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ahajournals.org\/doi\/pdf\/10.1161\/01.CIR.44.4.696","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,12]],"date-time":"2024-05-12T14:10:34Z","timestamp":1715523034000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ahajournals.org\/doi\/10.1161\/01.CIR.44.4.696"}},"subtitle":["A Study Using His Bundle Electrograms"],"short-title":[],"issued":{"date-parts":[[1971,10]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1971,10]]}},"alternative-id":["10.1161\/01.CIR.44.4.696"],"URL":"https:\/\/doi.org\/10.1161\/01.cir.44.4.696","relation":{},"ISSN":["0009-7322","1524-4539"],"issn-type":[{"value":"0009-7322","type":"print"},{"value":"1524-4539","type":"electronic"}],"subject":[],"published":{"date-parts":[[1971,10]]},"assertion":[{"value":"1971-04-16","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"1971-06-22","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"1971-10-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
