These advantages, particularly evident at elevated heart rates, highlight the importance of high temporal resolution for accurate cardiac imaging under stress conditions. The findings support prioritizing HFPS in clinical and research settings to improve tracking reliability and data accuracy.<\/jats:p>","DOI":"10.1152\/ajpheart.00817.2024","type":"journal-article","created":{"date-parts":[[2025,1,31]],"date-time":"2025-01-31T07:41:24Z","timestamp":1738309284000},"page":"H752-H760","update-policy":"https:\/\/doi.org\/10.1152\/aps-crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Elevated frame rates during exercise echocardiography improve speckle-tracking success rate and augment deformation values"],"prefix":"10.1152","volume":"328","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-3504-5650","authenticated-orcid":false,"given":"Fabian","family":"Spahiu","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0304hq317","id-type":"ROR","asserted-by":"publisher"}],"name":"Leibniz University Hannover","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle","family":"Ottlik","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0304hq317","id-type":"ROR","asserted-by":"publisher"}],"name":"Leibniz University Hannover","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-2797-6059","authenticated-orcid":false,"given":"Lars C.","family":"Helbig","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0304hq317","id-type":"ROR","asserted-by":"publisher"}],"name":"Leibniz University Hannover","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8005-285X","authenticated-orcid":false,"given":"Eric J.","family":"St\u00f6hr","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0304hq317","id-type":"ROR","asserted-by":"publisher"}],"name":"Leibniz University Hannover","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"24","reference":[{"key":"B1","first-page":"222","volume":"37","author":"Maleki M","year":"2012","journal-title":"Iran J Med Sci"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2005.10.040"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2006.08.031"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2014.11.003"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2012.10.008"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.3390\/jcm10102095"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1093\/ehjci\/jev058"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1152\/ajpheart.00104.2016"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2011.06.038"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehn004"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2014.07.012"},{"key":"B12","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2012.06.001"},{"key":"B13","doi-asserted-by":"publisher","DOI":"10.1113\/EP085081"},{"key":"B14","doi-asserted-by":"publisher","DOI":"10.1093\/ehjci\/jez041"},{"key":"B15","doi-asserted-by":"publisher","DOI":"10.1186\/1476-7120-7-21"},{"key":"B16","doi-asserted-by":"publisher","DOI":"10.1007\/s10554-024-03078-y"},{"key":"B17","doi-asserted-by":"publisher","DOI":"10.21037\/cdt.2017.07.03"},{"key":"B18","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCIMAGING.110.943522"}],"container-title":["American Journal of Physiology-Heart and Circulatory Physiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.physiology.org\/doi\/pdf\/10.1152\/ajpheart.00817.2024","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,11]],"date-time":"2025-04-11T14:45:39Z","timestamp":1744382739000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.physiology.org\/doi\/10.1152\/ajpheart.00817.2024"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4,1]]},"references-count":18,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2025,4,1]]}},"alternative-id":["10.1152\/ajpheart.00817.2024"],"URL":"https:\/\/doi.org\/10.1152\/ajpheart.00817.2024","relation":{},"ISSN":["0363-6135","1522-1539"],"issn-type":[{"value":"0363-6135","type":"print"},{"value":"1522-1539","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,4,1]]},"assertion":[{"value":"2024-11-21","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-12-17","order":1,"name":"revised","label":"Revised","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-01-15","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-03-10","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
