Standard 12\u2010lead electrocardiography, echocardiography, and P\u2010wave\u2010triggered signal\u2010averaged electrocardiography (P\u2010SAECG) were performed on all patients at the time of their entry into the study.<\/jats:p><jats:p><jats:italic>Results<\/jats:italic>: The mean follow\u2010up period was 61 \u00b1 13 months. Group 1 (n = 66) comprised patients in whom paroxysmal AF did not progress to persistent AF, and Group 2 (n = 36) comprised those who developed persistent AF. In Group 2 the patients were significantly older, and P\u2010wave dispersion, filtered P\u2010wave duration (FPD), and left atrial dimension were significantly higher than in Group 1 (p &lt; 0.05). The root mean square voltage for the last 30 ms of the filtered P\u2010wave was also significantly lower in Group 2 (p &lt; 0.05). Multivariate logistic regression analysis using these five factors identified left atrial dimension (odds ratio [OR] 2.29; 95% confidence interval [CI] 1.16\u20104.54; p = 0.02) and FPD (OR 2.71; 95% CI 1.78\u2010 4.13; p&lt; 0.01) as independent predictors of transition to persistent AF. Left atrial dimension \u2264 40 mm predicted progression to persistent AF with a sensitivity of 64%, specificity of 76%, positive predictive value of 59%, negative predictive value of 79%, and an accuracy of 71%. An FPD \u2264 150 ms predicted persistent AF with a sensitivity of 81%, specificity of 91%, positive predictive value of 88%, negative predictive value of 90%, and an accuracy of 87%. Filtered P\u2010wave duration was a significantly more sensitive and specific predictor than left atrial dimension (p &lt; 0.05).<\/jats:p><jats:p><jats:italic>Conclusion<\/jats:italic>: We conclude that FPD is a clinically useful predictor of progression from paroxysmal to persistent AF over the long term.<\/jats:p>","DOI":"10.1002\/clc.4950250206","type":"journal-article","created":{"date-parts":[[2007,6,27]],"date-time":"2007-06-27T13:47:02Z","timestamp":1182952022000},"page":"69-75","source":"Crossref","is-referenced-by-count":21,"title":["Investigation of the predictors of transition to persistent atrial fibrillation in patients with paroxysmal atrial fibrillation"],"prefix":"10.1002","volume":"25","author":[{"given":"Yasushi","family":"Koide","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masayuki","family":"Yotsukura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konomi","family":"Sakata","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hideaki","family":"Yoshino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyozo","family":"Ishikawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2006,12,5]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.31.6.888"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1536\/ihj.22.143"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-8703(83)90208-9"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.5105\/jse.20.27"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(99)80240-9"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM198709103171104"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(93)91015-A"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.17.4.622"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-116-1-1"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(87)80102-9"},{"key":"e_1_2_1_12_2","doi-asserted-by":"crossref","first-page":"1540","DOI":"10.1001\/jama.1981.03310400022019","article-title":"Mortality in insured population with atrial fibrillation","volume":"245","author":"Gajewski J","year":"1981","journal-title":"J Am Med Assoc"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM198204293061703"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.96.8.2612"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(90)90111-D"},{"key":"e_1_2_1_16_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.29.2.242"},{"key":"e_1_2_1_17_2","volume-title":"Echocardiography","author":"Feigenbaum H","year":"1981"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.148.3.6878708"},{"key":"e_1_2_1_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-8703(98)70030-4"},{"key":"e_1_2_1_20_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-69-1-13"},{"key":"e_1_2_1_21_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.54.4.553"},{"key":"e_1_2_1_22_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.83.1.162"},{"key":"e_1_2_1_23_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(91)90648-5"},{"key":"e_1_2_1_24_2","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(93)90381-A"},{"key":"e_1_2_1_25_2","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(96)00197-0"},{"key":"e_1_2_1_26_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(85)80232-1"}],"container-title":["Clinical Cardiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fclc.4950250206","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/clc.4950250206","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,18]],"date-time":"2023-11-18T12:58:00Z","timestamp":1700312280000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/clc.4950250206"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2002,2]]},"references-count":25,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2002,2]]}},"alternative-id":["10.1002\/clc.4950250206"],"URL":"https:\/\/doi.org\/10.1002\/clc.4950250206","archive":["Portico"],"relation":{},"ISSN":["0160-9289","1932-8737"],"issn-type":[{"value":"0160-9289","type":"print"},{"value":"1932-8737","type":"electronic"}],"subject":[],"published":{"date-parts":[[2002,2]]}}}
