Diagnosis is more difficult in this population because: the QT interval is prolonged by training; and the extreme bradycardia frequently observed in athletes makes the QT correction formula less accurate. Based on limited clinical data which tend to demonstrate that exercise, especially swimming, is a trigger for cardiac events, participation in any competitive sports practice is not supported by 2005 European guidelines. However, based on recent retrospective studies and adopting a different medical approach, involving the patient-athlete in shared decision making, the 2015 US guidelines are less restrictive, especially in asymptomatic genotype-positive\/phenotype-negative athletes. These guidelines also consider giving medical clearance to competitive sport participation in asymptomatic athletes with appropriate medical therapy.<\/jats:p>","DOI":"10.15420\/aer.2018.39.3","type":"journal-article","created":{"date-parts":[[2018,9,16]],"date-time":"2018-09-16T00:12:12Z","timestamp":1537056732000},"page":"187","source":"Crossref","is-referenced-by-count":45,"title":["Long-QT Syndrome and Competitive Sports"],"prefix":"10.15420","volume":"7","author":[{"given":"Fr\u00e9d\u00e9ric","family":"Schnell","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nathalie","family":"Behar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fran\u00e7ois","family":"Carr\u00e9","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"University of Rennes, Department of Sports Medicine University Hospital of Rennes, Inserm, LTSI-UMR 1099 Rennes, France","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"University of Rennes, Department of Cardiology University Hospital of Rennes, Inserm, LTSI-UMR 1099 Rennes, France","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"University of Rennes, Department of Sports Medicine University Hospital of Rennes, Inserm, LTSI-UMR 1099 Rennes, France","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"6096","reference":[{"key":"ref0","doi-asserted-by":"publisher","first-page":"1761","DOI":"10.1161\/CIRCULATIONAHA.109.863209","article-title":"Prevalence of the congenital long-QT syndrome","volume":"120","author":"Schwartz","year":"2009","unstructured":"1.
