Certain properties of the delta event are described that are useful in the recognition of this syndrome electrocardiographically. In about half the cases a ventricular conduction defect without QRS-interval prolongation was demonstrated to have accompanied the pre-excitation. The type of ventricular conduction defect produced depended upon the particular direction of spread of the pre-excitation wave. This and other findings are incompatible with the hypothesis that pre-excitation is due to accelerated atrioventricular conduction and favor the hypothesis that it is due to bridges, whether morphologic or electronic, between atria and ventricles.<\/jats:p>","DOI":"10.1161\/01.cir.18.3.355","type":"journal-article","created":{"date-parts":[[2012,6,11]],"date-time":"2012-06-11T23:15:32Z","timestamp":1339456532000},"page":"355-366","update-policy":"http:\/\/dx.doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":14,"title":["Ventricular Activation in the Pre-Excitation Syndrome (Wolff-Parkinson-White)"],"prefix":"10.1161","volume":"18","author":[{"given":"ROBERT P.","family":"GRANT","sequence":"first","affiliation":[{"name":"From the Clinic of General Medicine and Experimental Therapeutics, National Heart Institute, National Institutes of Health, Bethesda, Md."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"FRED B.","family":"TOMLINSON","sequence":"additional","affiliation":[{"name":"From the Clinic of General Medicine and Experimental Therapeutics, National Heart Institute, National Institutes of Health, Bethesda, Md."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JAMES K.","family":"VAN BUREN","sequence":"additional","affiliation":[{"name":"From the Clinic of General Medicine and Experimental Therapeutics, National Heart Institute, National Institutes of Health, Bethesda, Md."}],"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.18.3.355","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,12]],"date-time":"2024-05-12T12:59:34Z","timestamp":1715518774000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ahajournals.org\/doi\/10.1161\/01.CIR.18.3.355"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1958,9]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[1958,9]]}},"alternative-id":["10.1161\/01.CIR.18.3.355"],"URL":"https:\/\/doi.org\/10.1161\/01.cir.18.3.355","relation":{},"ISSN":["0009-7322","1524-4539"],"issn-type":[{"value":"0009-7322","type":"print"},{"value":"1524-4539","type":"electronic"}],"subject":[],"published":{"date-parts":[[1958,9]]},"assertion":[{"value":"1958-09-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
