The clinical history, physical exam, electrocardiogram, and radiographic findings of tamponade have poor sensitivities and even worse specificities. We use a clinical scenario to demonstrate how point\u2010of\u2010care cardiac ultrasound can diagnose impending cardiac tamponade in a clinically stable patient. The ultrasound finding we recommend is the flow velocity paradoxus, in which respiratory variation causes significant changes in transvalvular inflow velocities, which are exaggerated when tamponade is present. The management of a pericardial effusion depends on its physiologic effect, and point\u2010of\u2010care ultrasound directly measures that effect and expedites patient care.<\/jats:p>","DOI":"10.1002\/jum.14251","type":"journal-article","created":{"date-parts":[[2017,5,15]],"date-time":"2017-05-15T07:13:01Z","timestamp":1494832381000},"page":"2197-2201","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Point\u2010of\u2010Care Diagnosis of Cardiac Tamponade Identified by the Flow Velocity Paradoxus"],"prefix":"10.1002","volume":"36","author":[{"given":"William","family":"Shyy","sequence":"first","affiliation":[{"name":"Department of Emergency Medicine San Francisco General Hospital, University of California San Francisco California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roneesha S.","family":"Knight","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine San Francisco General Hospital, University of California San Francisco California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aaron","family":"Kornblith","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine San Francisco General Hospital, University of California San Francisco California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nathan A.","family":"Teismann","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, San Francisco Medical Center University of California San Francisco California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,5,15]]},"reference":[{"key":"e_1_2_5_2_1","first-page":"1581","article-title":"Cardiac tamponade on the edge","volume":"32","author":"Krishnasamy KP","year":"2015","journal-title":"Echo"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00246-005-0807-9"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(98)90060-2"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijcard.2009.06.048"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1172\/JCI104711"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/clc.4960260504"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11739-007-0007-0"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.297.16.1810"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.4330\/wjc.v3.i5.135"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/clc.4960220703"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/jhm.598"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.4070\/kcj.2012.42.11.725"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjmed.2013.03.022"}],"container-title":["Journal of Ultrasound in Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fjum.14251","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jum.14251","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,29]],"date-time":"2023-09-29T23:44:56Z","timestamp":1696031096000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/jum.14251"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,5,15]]},"references-count":13,"journal-issue":{"issue":"11","published-print":{"date-parts":[[2017,11]]}},"alternative-id":["10.1002\/jum.14251"],"URL":"https:\/\/doi.org\/10.1002\/jum.14251","archive":["Portico"],"relation":{},"ISSN":["0278-4297","1550-9613"],"issn-type":[{"value":"0278-4297","type":"print"},{"value":"1550-9613","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,5,15]]},"assertion":[{"value":"2016-12-20","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2017-02-02","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2017-05-15","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
