The initial history and physical examination often provide initial clues; however, some cases warrant further testing to determine the underlying cause. Autonomic function testing is a safe way to evaluate patients with syncope further, and to assess their parasympathetic and sympathetic nervous systems. Autonomic testing can help to diagnose several conditions, including orthostatic hypotension, delayed orthostatic hypotension, postural tachycardia syndrome and neutrally mediated syncope. Thus, when the cause of syncope is unclear, autonomic testing can help to assess the autonomic nervous system, stratify the risk of future episodes and to guide treatment decisions.<\/jats:p>","DOI":"10.1136\/practneurol-2015-001102","type":"journal-article","created":{"date-parts":[[2015,6,24]],"date-time":"2015-06-24T22:10:02Z","timestamp":1435183802000},"page":"346-351","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":11,"title":["Autonomic function testing: an important diagnostic test for patients with syncope"],"prefix":"10.1136","volume":"15","author":[{"given":"Pearl K","family":"Jones","sequence":"first","affiliation":[{"name":"Department of Neurology, UT Health Science Center San Antonio, San Antonio, Texas, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher H","family":"Gibbons","sequence":"additional","affiliation":[{"name":"Autonomic and Peripheral Nerve Laboratory, Department of Neurology, Beth Israel Deaconess Medical Center, Boston, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,6,24]]},"reference":[{"key":"2025090409335476000_15.5.346.1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehp298"},{"key":"2025090409335476000_15.5.346.2","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.2005.080713"},{"key":"2025090409335476000_15.5.346.3","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa012407"},{"key":"2025090409335476000_15.5.346.4","doi-asserted-by":"publisher","DOI":"10.1016\/j.pcad.2012.11.005"},{"key":"2025090409335476000_15.5.346.5","doi-asserted-by":"crossref","first-page":"115","DOI":"10.1016\/B978-0-444-52902-2.00007-2","article-title":"Testing the autonomic nervous system","volume":"115","author":"Freeman","year":"2013","journal-title":"Handb Clin Neurol"},{"key":"2025090409335476000_15.5.346.6","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-4598(199712)20:12<1561::AID-MUS11>3.0.CO;2-3"},{"key":"2025090409335476000_15.5.346.7","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.285.6346.916"},{"key":"2025090409335476000_15.5.346.8","unstructured":"Low PA .
