They were compared to 20 medical students of the same age. The subjects underwent an orthostatic test, deep breathing test, Valsalva maneuver, and a handgrip test. They were evaluated by an autoanamnestic questionnaire on vegetative symptoms and laboratory tests on blood chemistry. The heart rate of the PF group after 8 min of active standing was 32 \u00b1 15 beats\/min greater than at supine rest. The corresponding figure for the constrols was 23 \u00b1 7 beats\/min (p = 0.001). Twelve conscripts with PF (71%) presented sympathicotonic cardiovascular reaction on the orthostatic test (p &lt; 0.001). Four of these sympathicotonic conscripts and two other conscripts (total 35%) had an abnormal high index of dystonic symptoms (p = 0.01). The results suggest that young men with symptoms of PF have not only cardiovascular dystonic symptoms but also increased sympathetic nervous reactivity of the cardiovascular system.<\/jats:p>","DOI":"10.1002\/art.1790050405","type":"journal-article","created":{"date-parts":[[2007,2,15]],"date-time":"2007-02-15T00:18:32Z","timestamp":1171498712000},"page":"210-215","source":"Crossref","is-referenced-by-count":16,"title":["Cardiovascular functional disorder in primary fibromyalgia.
