A time-varying spectral analysis showed that during the first 550\u2005s, a significant power spectral density remained in the high-frequency (HF), low-frequency (LF) and VLF bands. From 550 to 675\u2005s, the HF oscillations totally vanished, and a marked progressive decay of the LF and VLF power density occurred. After 700 s the VLF undulations stopped and remaining small amplitude oscillations at 0.2 Hz coincided with the ventilator frequency. The VLF oscillations recorded in our case might be related to residual sympathetic vasomotor activity that progressively disappeared due to the extension of necrosis affecting the nervous centres of the lower part of the medulla and the first 2\u20133 cervical spine segments.<\/jats:p>","DOI":"10.1136\/bcr-2014-205677","type":"journal-article","created":{"date-parts":[[2015,4,1]],"date-time":"2015-04-01T09:58:59Z","timestamp":1427882339000},"page":"bcr2014205677","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":15,"title":["Residual vasomotor activity assessed by heart rate variability in a brain-dead case"],"prefix":"10.1136","volume":"2015","author":[{"given":"Calixto","family":"Machado","sequence":"first","affiliation":[{"name":"Department of Clinical Neurophysiology, Institute of Neurology and Neurosugery, Havana, Cuba"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mario","family":"Estevez","sequence":"additional","affiliation":[{"name":"Institute of Neurology, Havana, Cuba"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jesus","family":"Perez-Nellar","sequence":"additional","affiliation":[{"name":"Hermanos Amejeiras Hospital, Havana, Cuba"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam","family":"Schiavi","sequence":"additional","affiliation":[{"name":"Anesthesiology and Critical Care Medicine, Neurosciences Critical Care Division, Johns Hopkins Hospital, Baltimore, Maryland, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2015,4,1]]},"reference":[{"key":"2025082802143872000_2015.apr01_1.bcr2014205677.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2005.08.016"},{"key":"2025082802143872000_2015.apr01_1.bcr2014205677.2","doi-asserted-by":"publisher","DOI":"10.1097\/00003246-200202000-00007"},{"key":"2025082802143872000_2015.apr01_1.bcr2014205677.3","doi-asserted-by":"publisher","DOI":"10.1016\/S1566-0702(01)00263-6"},{"key":"2025082802143872000_2015.apr01_1.bcr2014205677.4","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.71.5.621"},{"key":"2025082802143872000_2015.apr01_1.bcr2014205677.5","doi-asserted-by":"publisher","DOI":"10.1016\/0013-4694(89)90121-1"},{"key":"2025082802143872000_2015.apr01_1.bcr2014205677.6","doi-asserted-by":"publisher","DOI":"10.1097\/00008506-200107000-00016"},{"key":"2025082802143872000_2015.apr01_1.bcr2014205677.7","unstructured":"Machado C .
