Cases were identified by multiple overlapping approaches. Medical records were reviewed to verify diagnosis, to determine stroke subtype and to determine selected risk factors.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results\u2014<\/jats:title>\n            <jats:p>A total of 343 individuals, aged \u226518 years, had a first stroke during the study period. Incidence was 144 per 100 000 person years; 81% ischemic infarction; 9% intracerebral hemorrhage; 7% subarachnoid hemorrhage; and 3% unknown. Fifty percent of the individuals were men. Mean age for ischemic infarction and intracerebral hemorrhage was 71 years for men and 73 years for women. Atrial fibrillation was previously known in 18% with first ischemic stroke or intracerebral hemorrhage and another 6% were diagnosed on routine admission ECG. Long-term ECG study (24 hours) found that 12% (18\/154) of the remaining individuals had paroxysmal atrial fibrillation.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>Incidence of first stroke in Iceland is similar to other Western countries. The high number of paroxysmal atrial fibrillation found during the 24-hour ECG suggests that atrial fibrillation may be underdiagnosed in patients with stroke.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/strokeaha.111.000222","type":"journal-article","created":{"date-parts":[[2013,5,10]],"date-time":"2013-05-10T05:15:42Z","timestamp":1368162942000},"page":"1714-1716","update-policy":"http:\/\/dx.doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":17,"title":["Incidence of First Stroke"],"prefix":"10.1161","volume":"44","author":[{"given":"Agust","family":"Hilmarsson","sequence":"first","affiliation":[{"name":"From the Department of Neurology (A.H., E.O.), and Department of Radiology (O.K.), Landspitali University Hospital, Reykjavik, Iceland; and University of Iceland, School of Medicine, Reykjavik, Iceland (E.O.)."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Olafur","family":"Kjartansson","sequence":"additional","affiliation":[{"name":"From the Department of Neurology (A.H., E.O.), and Department of Radiology (O.K.), Landspitali University Hospital, Reykjavik, Iceland; and University of Iceland, School of Medicine, Reykjavik, Iceland (E.O.)."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elias","family":"Olafsson","sequence":"additional","affiliation":[{"name":"From the Department of Neurology (A.H., E.O.), and Department of Radiology (O.K.), Landspitali University Hospital, Reykjavik, Iceland; and University of Iceland, School of Medicine, Reykjavik, Iceland (E.O.)."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1093\/bmb\/ldp028"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/strokeaha.107.491779"},{"key":"e_1_3_2_4_2","first-page":"373","article-title":"Stroke incidence, prevalence, and survival: secular trends in Rochester, Minnesota, through 1989.","volume":"27","author":"Brown RD","year":"1996","unstructured":"Brown RD, Whisnant JP, Sicks JD, O\u2019Fallon WM, Wiebers DO.
