This method combines recurrence-based plots with convolutional neural networks. Moreover, we devised a novel plot, with which our classification achieved specificity of 97.5%, sensitivity of 98.4%, and accuracy of 98.6%. These criteria are higher than previously reported results for measurements obtained with blood pressure monitors and are almost equal to statistical measures for methods based on electrocardiographs and photoplethysmographs.<\/jats:p>","DOI":"10.1063\/5.0212068","type":"journal-article","created":{"date-parts":[[2025,3,14]],"date-time":"2025-03-14T16:51:19Z","timestamp":1741971079000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":3,"title":["Detection of atrial fibrillation from pulse waves using convolution neural networks and recurrence-based plots"],"prefix":"10.1063","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2625-2508","authenticated-orcid":false,"given":"Hiroyuki","family":"Kitajima","sequence":"first","affiliation":[{"name":"Faculty of Engineering and Design, Kagawa University 1 , 2217-20, Hayashi, Takamatsu, Kagawa 761-0396,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9071-9101","authenticated-orcid":false,"given":"Kentaro","family":"Takeda","sequence":"additional","affiliation":[{"name":"Faculty of Engineering and Design, Kagawa University 1 , 2217-20, Hayashi, Takamatsu, Kagawa 761-0396,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-0849-6912","authenticated-orcid":false,"given":"Makoto","family":"Ishizawa","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Kagawa University 2 , 1750-1 Ikenobe, Miki-cho, Kita-gun, Kagawa 761-0793,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4602-9816","authenticated-orcid":false,"given":"Kazuyuki","family":"Aihara","sequence":"additional","affiliation":[{"name":"International Research Center for Neurointelligence, The University of Tokyo 3 , 7-3-1 Hongo Bunkyo-ku, Tokyo 113-0033,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-1907-6120","authenticated-orcid":false,"given":"Tetsuo","family":"Minamino","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Kagawa University 2 , 1750-1 Ikenobe, Miki-cho, Kita-gun, Kagawa 761-0793,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2025,3,14]]},"reference":[{"key":"2025031416511409400_c1","doi-asserted-by":"publisher","first-page":"465","DOI":"10.1016\/j.eswa.2018.08.011","volume":"115","year":"2019","journal-title":"Expert Syst.
