Guidelines recommend at least 24 hours of ECG monitoring after stroke. However, it is unclear how often this is done in routine practice.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods\u2014<\/jats:title>\n            <jats:p>In this longitudinal cohort study using data from the Ontario Stroke Registry, we analyzed consecutive patients presenting to designated stroke centers in Ontario, Canada (2003\u20132013) with a first acute ischemic stroke or transient ischemic attack (TIA) in sinus rhythm and without known atrial fibrillation. The primary outcome was the proportion of patients who received at least 24-hour Holter monitoring within 30 days after stroke\/TIA. Secondary analyses assessed total duration of ECG monitoring completed within 90 days after stroke\/TIA, temporal trends in monitoring use, and use of Holter monitoring relative to echocardiography.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results\u2014<\/jats:title>\n            <jats:p>Among 17\u2009398 consecutive eligible patients (mean age 68.8\u00b114.3 years), 30.6% had at least 24 hours of Holter monitoring within 30 days after stroke\/TIA. Less than 1% of patients received prolonged monitoring beyond 48 hours. The median time to start monitoring was 9 days poststroke (interquartile range 3\u201325). Stroke\/TIA patients were nearly twice as likely to receive an echocardiogram than a Holter monitor within 90 days (odds ratio 1.8, 95% confidence interval 1.67\u20132.01).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>Less than one third of patients in our cohort received guideline-recommended 24-hour Holter monitoring, and &lt;1% received prolonged ambulatory ECG monitoring. These findings highlight a modifiable evidence-practice gap that likely contributes to an overdiagnosis of strokes as cryptogenic, an underdiagnosis of atrial fibrillation, and missed anticoagulant treatment opportunities for secondary stroke prevention.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/strokeaha.115.012195","type":"journal-article","created":{"date-parts":[[2016,7,13]],"date-time":"2016-07-13T02:54:41Z","timestamp":1468378481000},"page":"1982-1989","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":55,"title":["Underutilization of Ambulatory ECG Monitoring After Stroke and Transient Ischemic Attack"],"prefix":"10.1161","volume":"47","author":[{"given":"Jodi D.","family":"Edwards","sequence":"first","affiliation":[{"name":"From the Sunnybrook Research Institute and Hurvitz Brain Sciences Program (J.D.E., D.J.G.), L.C.
