Two hundred and thirty\u2010one boxers, randomly selected or investigated at dog shows, were examined by phonocardiography by two veterinarians and classified on the basis of the characteristics of their murmurs into categories 0 to 4. No murmur was detected in 23 per cent of the dogs, murmurs classified as category 1 were diagnosed in 25 per cent of the dogs, as category 2\u00a0in 46 per cent, as category 3\u00a0in 7 per cent cent, and two dogs had category 4\u00a0murmurs. In 55 per cent of the dogs, primarily those with very soft murmurs, there was some variation in the intensity of the murmur from beat to beat. The prevalence of cardiac murmurs among Norwegian and Swedish boxers was high and similar to the prevalence reported in Great Britain.<\/jats:p>","DOI":"10.1136\/vr.147.6.152","type":"journal-article","created":{"date-parts":[[2010,10,8]],"date-time":"2010-10-08T14:05:40Z","timestamp":1286546740000},"page":"152-156","source":"Crossref","is-referenced-by-count":17,"title":["Prevalence of murmurs consistent with aortic stenosis among boxer dogs in Norway and Sweden"],"prefix":"10.1002","volume":"147","author":[{"given":"R.","family":"Heiene","sequence":"first","affiliation":[{"name":"Department of Small Animal Clinical Sciences PO Box 8146 Dep 0033 Oslo Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Indreb\u00f8","sequence":"additional","affiliation":[{"name":"The Norwegian Kennel Club Norwegian School of Veterinary Science PO Box 8146 Dep 0033 Oslo Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Kvart","sequence":"additional","affiliation":[{"name":"Department of Physiology Agricultural University of Sweden SLU PO Box 7045 750 07 Uppsala Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.
