We used continuous electronic heart rate corrected QT interval (QTc) monitoring to screen for interval prolongation in a cohort of hospitalized neonates to identify those at a risk of having LQTS. We hypothesized that this screening method would yield an acceptable positive predictive value (PPV).<\/jats:p><jats:p>\n            Study Design\u2003A cohort of 589 infants hospitalized in a level II neonatal intensive care unit were screened through continuous electronic QTc monitoring linked to an investigator-designed, computerized data sniffer. Screening was conducted from days-of-life 3 through 7 or until hospital discharge. The data sniffer alerted investigators for a 24-hour average QTc of \u2265475 ms. Positively screened patients were further evaluated with 12-lead ECG.<\/jats:p><jats:p>\n            Results\u2003Positive screens were obtained in 5.6% of patients, all of whom had negative follow-up ECG testing (PPV\u2009=\u20090%). Furthermore, one-quarter of positively screened neonates underwent echocardiography based on ECG findings, none of which identified clinically relevant pathology.<\/jats:p><jats:p>\n            Conclusion\u2003Electronic monitoring of QTc in hospitalized neonates during the first week of life was not an efficient way to identify those at a risk of having LQTS. Conversely, screening triggered unnecessary testing.<\/jats:p>","DOI":"10.1055\/s-0039-1678605","type":"journal-article","created":{"date-parts":[[2019,2,4]],"date-time":"2019-02-04T18:42:42Z","timestamp":1549305762000},"page":"322-325","source":"Crossref","is-referenced-by-count":3,"title":["Universal Electrocardiographic Screening for Long QT Syndrome in Hospitalized Neonates"],"prefix":"10.1055","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0537-5106","authenticated-orcid":false,"given":"Bethany D.","family":"Kaemingk","sequence":"additional","affiliation":[{"name":"Division of Neonatal Medicine, Mayo Clinic, Rochester, Minnesota"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Timothy J.","family":"Ulrich","sequence":"additional","affiliation":[{"name":"Division of Neonatal\u2013Perinatal Medicine, St. Luke's Health System, Boise, Idaho"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Man","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Information Technology, Multidisciplinary Epidemiology and Translational Research in Intensive Care, Mayo Clinic, Rochester, Minnesota"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William A.","family":"Carey","sequence":"additional","affiliation":[{"name":"Division of Neonatal Medicine, Mayo Clinic, Rochester, Minnesota"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marc A.","family":"Ellsworth","sequence":"additional","affiliation":[{"name":"Division of Neonatology, Banner \u2013 University Medical Center Phoenix, Phoenix, Arizona"},{"name":"Division of Neonatology, Cardon Children's Medical Center, Banner Health, Mesa, Arizona"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2019,2,4]]},"container-title":["American Journal of Perinatology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0039-1678605.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,2,18]],"date-time":"2020-02-18T18:37:15Z","timestamp":1582051035000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0039-1678605"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,2,4]]},"references-count":0,"journal-issue":{"issue":"03","published-online":{"date-parts":[[2020,2,18]]},"published-print":{"date-parts":[[2020,2]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0039-1678605","relation":{},"ISSN":["0735-1631","1098-8785"],"issn-type":[{"type":"print","value":"0735-1631"},{"type":"electronic","value":"1098-8785"}],"subject":[],"published":{"date-parts":[[2019,2,4]]}}}
