The evidence is extremely limited with regard to the safety and effectiveness of this therapy. In Australia, half of the eight ambulance services include SDC within their clinical practice guidelines for the management of poorly perfused SVT; however the degree of variation in the application of SDC across these guidelines suggests a need to quantify the practice. This case provides a previously unreported example of the safety and effectiveness of prehospital SDC for SVT (with poor perfusion precipitated by a Valsalva Maneuver) by Victorian paramedics, and discusses the available literature regarding the effectiveness and safety of this practice.<\/jats:p><jats:p><jats:mixed-citation id=\"S1049023X13000174_ref\" publication-type=\"journal\"><jats:name name-style=\"western\"><jats:surname>Smith<\/jats:surname><jats:given-names>G<\/jats:given-names><\/jats:name>, <jats:name name-style=\"western\"><jats:surname>Taylor<\/jats:surname><jats:given-names>D<\/jats:given-names><\/jats:name>, <jats:name name-style=\"western\"><jats:surname>Morgans<\/jats:surname><jats:given-names>A<\/jats:given-names><\/jats:name>, <jats:name name-style=\"western\"><jats:surname>Cameron<\/jats:surname><jats:given-names>P<\/jats:given-names><\/jats:name>. <jats:article-title>Prehospital synchronized electrical cardioversion of a poorly perfused SVT patient by paramedics<\/jats:article-title>. <jats:source>Prehosp Disaster Med<\/jats:source>. <jats:year>2013<\/jats:year>;<jats:volume>28<\/jats:volume>(<jats:issue>3<\/jats:issue>):<jats:fpage>1<\/jats:fpage>-<jats:lpage>4<\/jats:lpage><\/jats:mixed-citation>.<\/jats:p>","DOI":"10.1017\/s1049023x13000174","type":"journal-article","created":{"date-parts":[[2013,3,14]],"date-time":"2013-03-14T10:19:02Z","timestamp":1363256342000},"page":"301-304","source":"Crossref","is-referenced-by-count":14,"title":["Prehospital Synchronized Electrical Cardioversion of a Poorly Perfused SVT Patient by Paramedics"],"prefix":"10.1017","volume":"28","author":[{"given":"Gavin","family":"Smith","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David McD","family":"Taylor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amee","family":"Morgans","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Cameron","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2013,3,14]]},"reference":[{"key":"S1049023X13000174_ref13","doi-asserted-by":"publisher","DOI":"10.1097\/01.CCM.0000048627.39686.79"},{"key":"S1049023X13000174_ref2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(02)11315-8"},{"key":"S1049023X13000174_ref22","unstructured":"Anon.
