This study evaluated right atrial electrocardiography as a method of accurately placing the catheter tip in 34 patients over a period of 22 months. An electrocardiograph adaptor was connected to the catheter and the tip advanced into a central vein until a biphasic P wave was identified. In 31 of 34 patients the characteristic P wave changes were observed and the position of the catheter tip confirmed by screening to be in the superior vena cava. Right atrial electrocardiography is an accurate, reliable and rapid method of positioning the tip of a central venous catheter, and avoids or reduces exposure to radiation.<\/jats:p>","DOI":"10.1002\/bjs.1800811113","type":"journal-article","created":{"date-parts":[[2007,3,3]],"date-time":"2007-03-03T19:50:21Z","timestamp":1172951421000},"page":"1604-1605","source":"Crossref","is-referenced-by-count":16,"title":["Right atrial electrocardiography: A technique for the placement of central venous catheters for chemotherapy or intravenous nutrition"],"prefix":"10.1093","volume":"81","author":[{"given":"M","family":"Madan","sequence":"first","affiliation":[{"name":"University Department of Surgery, Cookridge Hospital , Leeds,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M V","family":"Shah","sequence":"additional","affiliation":[{"name":"University Department of Anaesthetics, The General Infirmary, Cookridge Hospital , Leeds,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D J","family":"Alexander","sequence":"additional","affiliation":[{"name":"University Department of Surgery, Cookridge Hospital , Leeds,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C","family":"Taylor","sequence":"additional","affiliation":[{"name":"Department of Medical Physics, Cookridge Hospital , Leeds,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M J","family":"McMahon","sequence":"additional","affiliation":[{"name":"University Department of Surgery, Cookridge Hospital , Leeds,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[1994,11,1]]},"reference":[{"key":"2024092813111381500_bib1","doi-asserted-by":"crossref","first-page":"390","DOI":"10.1213\/00000539-196607000-00005","article-title":"Air embolism during neurosurgery - a new method of treatment","volume":"45","author":"Michenfelder","year":"1966","journal-title":"Anesth Analg"},{"key":"2024092813111381500_bib2","doi-asserted-by":"crossref","first-page":"200","DOI":"10.1213\/00000539-198410000-00014","article-title":"EKG guided placement of CVP catheters via arm veins: success rate, placement time and optimal conductive solutions","volume":"63","author":"Colley","year":"1984","journal-title":"Anesth Analg"},{"key":"2024092813111381500_bib3","doi-asserted-by":"crossref","first-page":"1353","DOI":"10.1001\/jama.1969.03160080017004","article-title":"Air embolism during neurosurgery.
