Heart sounds of 20 dogs were auscultated\n                    <jats:italic>in vivo<\/jats:italic>\n                    (on-line) and recorded with dPCGs by two authors using a Welch Allyn Meditron Stethoscope System. Sound recordings were auscultated off-line and blindly by four different observers having various auscultatory experiences, then listened to while viewing dPCGs. The results were compared to echocardiographic diagnoses. There was a significant agreement (p &lt; 0.001) between on-line and off-line auscultatory findings regarding the four observers, ranging from 45% to 75% (weighted kappa values: 0.72 to 0.87). The best agreement was achieved by Observer 1 having the highest experience. Significant differences (p &lt; 0.05) were found between Observer 1 and Observer 4 (with the lowest experience) in judging the quality of the murmurs during the off-line and blind auscultation. However, there were only minimal differences (95% to 100% agreements) in dPCG analyses among the four observers regarding intensity and quality of the murmurs while simultaneously listening to and viewing the dPCGs. Significant correlations were found between the traditional \u20180 to 6 scale\u2019 and a new \u20180 to 3 scale\u2019 murmur intensity gradings by all observers (correlation coefficients 0.640 to 0.908; p &lt; 0.01 to p &lt; 0.001). Analysis of dPCGs might be a valuable, additional tool helping with the diagnosis of canine cardiac murmurs, especially for those with less cardiological experience.\n                  <\/jats:p>","DOI":"10.1556\/avet.59.2011.1.3","type":"journal-article","created":{"date-parts":[[2011,3,2]],"date-time":"2011-03-02T10:54:14Z","timestamp":1299063254000},"page":"23-35","source":"Crossref","is-referenced-by-count":17,"title":["Sound recording and digital phonocardiography of cardiac murmurs in dogs by using a sensor-based electronic stethoscope"],"prefix":"10.1556","volume":"59","author":[{"given":"K\u00e1roly","family":"V\u00f6r\u00f6s","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ingo","family":"Nolte","sequence":"additional","affiliation":[{"name":"1 University of Veterinary Medicine Hanover Small Animal Clinic B\u00fcnteweg 9 D-30559 Hanover Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephan","family":"Hungerb\u00fchler","sequence":"additional","affiliation":[{"name":"1 University of Veterinary Medicine Hanover Small Animal Clinic B\u00fcnteweg 9 D-30559 Hanover Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jen\u0151","family":"Reiczigel","sequence":"additional","affiliation":[{"name":"3 Szent Istv\u00e1n University Department of Biomathematics and Informatics, Faculty of Veterinary Science Budapest Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Ehlers","sequence":"additional","affiliation":[{"name":"2 University of Veterinary Medicine Hanover E-Learning Consultant B\u00fcnteweg 9 D-30559 Hanover Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guy","family":"Tater","sequence":"additional","affiliation":[{"name":"1 University of Veterinary Medicine Hanover Small Animal Clinic B\u00fcnteweg 9 D-30559 Hanover Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reinhard","family":"Mischke","sequence":"additional","affiliation":[{"name":"1 University of Veterinary Medicine Hanover Small Animal Clinic B\u00fcnteweg 9 D-30559 Hanover Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tanja","family":"Zimmering","sequence":"additional","affiliation":[{"name":"1 University of Veterinary Medicine Hanover Small Animal Clinic B\u00fcnteweg 9 D-30559 Hanover Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias","family":"Schneider","sequence":"additional","affiliation":[{"name":"4 Justus-Liebig University Giessen Small Animal Clinic, Veterinary Faculty Giessen Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"425","reference":[{"key":"1","volume-title":"Categorical Data Analysis","author":"Agresti A.","year":"1991"},{"key":"2","volume-title":"Practical Statistics for Medical Research","author":"Altman D.
