Vasodepressor syncope and the diagnostic accuracy of the head-up tilt test with sublingual glyceryl trinitrate.
Thirteen syncopal subjects and thirteen asymptomatic controls were examined by head-up tilt (HUT) with and without sublingual GTN. Adding GTN to HUT improved the sensitivity of the test (8 % to 46%) but decreased specificity (100 % to 54 %).
