ECGs were compared for quality score, heart rate, and ECG waves, complexes, and intervals. Quality scores were based on the presence or absence of baseline undulation and tremor artifacts using a 3-point scoring system (lowest possible = 0; highest possible = 3).

Standard ECG quality was superior to smartphone-based ECG quality, with no agreement in the quality between devices (\u03ba coefficient, \u20130.0062). There was good agreement for heart rate with mean difference 2.86 beats\/min (CI, \u20133.44 to 9.16) between the standard and smartphone ECGs. Good agreement was observed for P wave amplitude with mean difference 0.02 mV (CI, \u20130.01 to 0.05), QRS duration with mean difference \u201310.5 ms (CI, \u201320.96 to \u20130.04), QT interval with mean difference \u201327.14 ms (CI, \u201359.36 to 5.08), T wave duration with mean difference \u201330.00 ms (CI, \u201366.727 to 6.727), and T wave amplitude with mean difference \u20130.07 mV (CI, \u20130.22 to 0.08) between the 2 devices.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>CLINICAL RELEVANCE<\/jats:title>\n<jats:p>Our findings indicate good agreement between standard and smartphone ECG for most parameters, although 35% of smartphone ECGs were uninterpretable.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/javma.23.02.0126","type":"journal-article","created":{"date-parts":[[2023,5,22]],"date-time":"2023-05-22T12:29:44Z","timestamp":1684758584000},"page":"1-5","source":"Crossref","is-referenced-by-count":5,"title":["Overall good agreement of smartphone-based and standard base-apex electrocardiography in healthy sheep"],"prefix":"10.2460","volume":"261","author":[{"given":"Ailbhe","family":"King","sequence":"first","affiliation":[{"name":"Department of Population Health and Pathobiology, College of Veterinary Medicine, North Carolina State University, Raleigh, NC"},{"name":"Center for Integrative Mammalian Research, Department of Clinical Sciences, School of Veterinary Medicine, Ross University, Basseterre, St. Kitts, West Indies"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kerry E.","family":"Rolph","sequence":"additional","affiliation":[{"name":"Center for Integrative Mammalian Research, Department of Clinical Sciences, School of Veterinary Medicine, Ross University, Basseterre, St. Kitts, West Indies"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Loveness","family":"Dzikiti","sequence":"additional","affiliation":[{"name":"School of Health Systems and Public Health, University of Pretoria, Pretoria, South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sarah M.","family":"Cavanaugh","sequence":"additional","affiliation":[{"name":"Center for Integrative Mammalian Research, Department of Clinical Sciences, School of Veterinary Medicine, Ross University, Basseterre, St. Kitts, West Indies"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1272","reference":[{"issue":"2","key":"ref1","series-title":"J Am Vet Med Assoc","first-page":"189","article-title":"Detection of heart rate and rhythm with a smartphone-based electrocardiograph versus a reference standard electrocardiograph in dogs and cats","volume":"249","author":"Kraus MS","year":"2016","unstructured":"Kraus MS, Gelzer AR, Rishniw M.
