The objective of this study was to assess whether computer-stored digital sound recordings can be used to distinguish innocent from pathologic systolic murmurs.<\/jats:p><jats:p>METHODS. Recordings of 55 children aged 1 month to 19 years were made remotely with the use of a digital stethoscope and were e-mailed to a computer in our center for later assessment. Eight-second recordings were made by a physician in 2 to 4 locations on the chest. Three cardiologists who were blinded to the diagnosis reviewed the recordings independently using stethophones to assess the splitting of the second heart sound and whether murmurs were innocent or pathologic. Diagnoses were confirmed with echocardiography.<\/jats:p><jats:p>RESULTS. Seventeen children had innocent murmurs and 38 had pathologic murmurs. For the 3 cardiologists, sensitivity was 0.87 to 1.0, specificity was 0.82 to 0.88, negative predictive value was 0.75 to 1.0, and positive predictive value was 0.93 to 0.95. Assessment of splitting of second heart sound was highly accurate.<\/jats:p><jats:p>CONCLUSIONS. Digital recordings of children\u2019s heart sounds allow reliable differentiation between innocent and pathologic murmurs. Use of this technology may allow remote diagnosis of childhood murmurs and avoid the expense and stress of travel to pediatric cardiology centers for some children. Cardiologists who use recordings should assess their diagnostic accuracy before clinical application.<\/jats:p>","DOI":"10.1542\/peds.2006-1557","type":"journal-article","created":{"date-parts":[[2006,12,1]],"date-time":"2006-12-01T17:33:20Z","timestamp":1164994400000},"page":"2322-2325","source":"Crossref","is-referenced-by-count":28,"title":["Assessing Children\u2019s Heart Sounds at a Distance With Digital Recordings"],"prefix":"10.1542","volume":"118","author":[{"given":"John P.","family":"Finley","sequence":"first","affiliation":[{"name":"Children\u2019s Heart Centre, Izaak Walton Killam Health Centre, Halifax, Nova Scotia, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew E.","family":"Warren","sequence":"additional","affiliation":[{"name":"Children\u2019s Heart Centre, Izaak Walton Killam Health Centre, Halifax, Nova Scotia, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geoffrey P.","family":"Sharratt","sequence":"additional","affiliation":[{"name":"Children\u2019s Heart Centre, Izaak Walton Killam Health Centre, Halifax, Nova Scotia, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minoli","family":"Amit","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Dalhousie University, Halifax, Nova Scotia, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"417","published-online":{"date-parts":[[2006,12,1]]},"reference":[{"key":"2021120823092817300_R1","doi-asserted-by":"crossref","unstructured":"Finley JP, Justo R.
