A blunted TRH-TSH test, suggestive of thyrotoxicosis, was found in 5 patients in Group I, 8 patients in Group II, and 2 patients in Group III. The diagnosis of hyperthyroidism was confirmed in 8 patients (by repeated TRH-TSH test and scintigraphy): 4 pa tients in Group I (12.1%) and 4 patients in Group II (12.9%). All of them had a nonvalvular atrial fibrillation. Thyrotoxicosis should not be recognized in 6 of them if TRH-TSH test was not performed, because peripheral hormone levels were normal. Five of these 8 patients with thyrotoxicosis had reversion to sinus rhythm after treatment with carbimazole, either spontaneously or after car dioversion. This outcome prevented prolongation of anticoagulant therapy for an indefinite time.<\/jats:p>","DOI":"10.1177\/000331978803901108","type":"journal-article","created":{"date-parts":[[2007,11,26]],"date-time":"2007-11-26T17:46:29Z","timestamp":1196099189000},"page":"981-985","source":"Crossref","is-referenced-by-count":12,"title":["Occult
