Patients were monitored continuously for the first 7 days following surgery.<\/jats:p>\n          <jats:p>Thirty-seven patients (74%) experienced a total of 66 episodes of arrhythmia. Supra-ventricualr arrhythmias were the most common (43 of 66; 65%). The most frequent specific arrhythmia was atrial fibrillation (21 of 66; 32%). Arrhythmias occurred 77% of the time within the first 48 hours of surgery.<\/jats:p>\n          <jats:p>Of 25 factors evaluated preoperatively in each patient, only two were found to predispose to postoperative arrhythmias. These were: (1) previous cardiac surgery; and (2) elevated blood urea nitrogen.<\/jats:p>\n          <jats:p>There were four hospital deaths, representinig a hospital mortality of 8%. No deaths were due to a primary arrhythmia.<\/jats:p>\n          <jats:p>It is concluded that whereas arrhythmias are a very common complication of cardiac valve replacement, early detection and treatment has lessened their significance as a cause of postoperative mortality and morbidity.<\/jats:p>","DOI":"10.1161\/01.cir.45.5.1018","type":"journal-article","created":{"date-parts":[[2012,6,11]],"date-time":"2012-06-11T23:56:43Z","timestamp":1339459003000},"page":"1018-1023","update-policy":"http:\/\/dx.doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":35,"title":["Arrhythmias following Cardiac Valve Replacement"],"prefix":"10.1161","volume":"45","author":[{"given":"ROGER","family":"SMITH","sequence":"first","affiliation":[{"name":"From the Departments of Medicine and Surgery, Peter Bent Brigham Hospital, and Harvard Medical School, Boston, Massachusetts."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"WILLIAM","family":"GROSSMAN","sequence":"additional","affiliation":[{"name":"From the Departments of Medicine and Surgery, Peter Bent Brigham Hospital, and Harvard Medical School, Boston, Massachusetts."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"LEWIS","family":"JOHNSON","sequence":"additional","affiliation":[{"name":"From the Departments of Medicine and Surgery, Peter Bent Brigham Hospital, and Harvard Medical School, Boston, Massachusetts."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"HERMAN","family":"SEGAL","sequence":"additional","affiliation":[{"name":"From the Departments of Medicine and Surgery, Peter Bent Brigham Hospital, and Harvard Medical School, Boston, Massachusetts."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JOHN","family":"COLLINS","sequence":"additional","affiliation":[{"name":"From the Departments of Medicine and Surgery, Peter Bent Brigham Hospital, and Harvard Medical School, Boston, Massachusetts."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JAMES","family":"DALEN","sequence":"additional","affiliation":[{"name":"From the Departments of Medicine and Surgery, Peter Bent Brigham Hospital, and Harvard Medical School, Boston, Massachusetts."}],"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.45.5.1018","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,12]],"date-time":"2024-05-12T13:56:05Z","timestamp":1715522165000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ahajournals.org\/doi\/10.1161\/01.CIR.45.5.1018"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1972,5]]},"references-count":0,"journal-issue":{"issue":"5","published-print":{"date-parts":[[1972,5]]}},"alternative-id":["10.1161\/01.CIR.45.5.1018"],"URL":"https:\/\/doi.org\/10.1161\/01.cir.45.5.1018","relation":{},"ISSN":["0009-7322","1524-4539"],"issn-type":[{"value":"0009-7322","type":"print"},{"value":"1524-4539","type":"electronic"}],"subject":[],"published":{"date-parts":[[1972,5]]},"assertion":[{"value":"1971-08-17","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"1971-12-22","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"1972-05-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
