They were classified into the following WPW types: anterior right ventricular pre-excitation (Type I) - six patients; posterior right ventricular pre-excitation (Type II) - six patients; posterior left ventricular pre-excitation (Type III) - fourteen patients. Twenty-three patients were in WPW at the time of study. Four patients with Type I WPW had abnormal systolic motion of the interventricular septum: three paradoxical and one flat. Patients with Type II and Type III WPW had no septal motion abnormalities related to pre-excitation. Three patients had intermittent WPW, Type III; in all three only minor changes in normal septal motion were apparent on WPW beats. Associated cardiac abnormalities were evident in six patients: two mitral prolapse (one Type II WPS and one Tpe III); one idiopathic hypertrophic subaortic stenosis (Type III); one congestive cardiomyopathy (Type III); one hypertrophic nonobstructive cardiomyopathy (Type I); and one atrial septal defect (Type II). We conclude that abnormal interventricular septal motion may occur with Type I WPW abnormality. Other abnormalities are detectable by echocardiography in a high proportion of WPW patients, but do not appear to be associated with any single Wolff-Parkinson-White type.<\/jats:p>","DOI":"10.1161\/01.cir.53.6.943","type":"journal-article","created":{"date-parts":[[2012,6,11]],"date-time":"2012-06-11T23:57:40Z","timestamp":1339459060000},"page":"943-946","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":46,"title":["Echocardiography in Wolff-Parkinson-White syndrome."],"prefix":"10.1161","volume":"53","author":[{"given":"M S","family":"Chandra","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R E","family":"Kerber","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D D","family":"Brown","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D C","family":"Funk","sequence":"additional","affiliation":[],"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.53.6.943","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,12]],"date-time":"2024-05-12T14:16:07Z","timestamp":1715523367000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ahajournals.org\/doi\/10.1161\/01.CIR.53.6.943"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1976,6]]},"references-count":0,"journal-issue":{"issue":"6","published-print":{"date-parts":[[1976,6]]}},"alternative-id":["10.1161\/01.CIR.53.6.943"],"URL":"https:\/\/doi.org\/10.1161\/01.cir.53.6.943","relation":{},"ISSN":["0009-7322","1524-4539"],"issn-type":[{"value":"0009-7322","type":"print"},{"value":"1524-4539","type":"electronic"}],"subject":[],"published":{"date-parts":[[1976,6]]},"assertion":[{"value":"1976-06-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
