In 10 normal controls studied in a similar fashion there was an average fall of 5 mmHg. The difference in response between responders and controls\/non-responders was highly significant ( P&lt; 0.001). A review of the literature is presented, for comparison. It is considered that a psychological challenge under hypnosis may have important implications for diagnosis and therapy in some patients considered to have the hyperventilation syndrome.\n                  <\/jats:p>","DOI":"10.1177\/014107688607900206","type":"journal-article","created":{"date-parts":[[2017,1,12]],"date-time":"2017-01-12T23:58:57Z","timestamp":1484265537000},"page":"76-83","source":"Crossref","is-referenced-by-count":42,"title":["Physiological Responses to Psychological Challenge under Hypnosis in Patients Considered to Have the Hyperventilation Syndrome: Implications for Diagnosis and Therapy"],"prefix":"10.1177","volume":"79","author":[{"given":"L J","family":"Freeman","sequence":"first","affiliation":[{"name":"Cardiac Department, Charing Cross Hospital, London W6 8RF"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"Conway","sequence":"additional","affiliation":[{"name":"Cardiac Department, Charing Cross Hospital, London W6 8RF"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P G F","family":"Nixon","sequence":"additional","affiliation":[{"name":"Cardiac Department, Charing Cross Hospital, London W6 8RF"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1986,2,1]]},"reference":[{"key":"bibr-bibr1-014107688607900206","doi-asserted-by":"publisher","DOI":"10.1176\/ajp.101.2.141"},{"key":"bibr-bibr2-014107688607900206","doi-asserted-by":"publisher","DOI":"10.1037\/h0073754"},{"key":"bibr-bibr3-014107688607900206","first-page":"111","volume":"128","author":"Motta PE","year":"1971","journal-title":"Arch Sci Med"},{"key":"bibr-bibr4-014107688607900206","first-page":"419","volume":"117","author":"Beckman K.","year":"1915","journal-title":"Dtsch Arch Klin Med"},{"key":"bibr-bibr5-014107688607900206","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8986.1980.tb02293.x"},{"key":"bibr-bibr6-014107688607900206","doi-asserted-by":"publisher","DOI":"10.1097\/00006842-196401000-00007"},{"key":"bibr-bibr7-014107688607900206","volume-title":"The Lung","author":"Comroe JH","year":"1967","edition":"2"},{"key":"bibr-bibr8-014107688607900206","unstructured":"Svebak PS.
