Fig. Two minutes after administration of 400 µg sublingual nitroglycerin. A fall in SBP, 2 minutes after 70° head-up tilt, is associated with a positive test result; however, this cannot be considered as a sole predictor of a positive TTT. 3. CONCLUSIONS: The risk of a recurrence of syncope after a positive tilt-table test can be predicted with simple pretest and intratest variables. However, in our study, a false-positive result is a positive tilt test with a rise of HR of ≤18 bpm. A normal person's blood pressure will not drop dramatically while standing, because the body will compensate for this posture with a slight increase in heart rate and constriction of the blood vessels in the legs. Tilt-table test and follow-up results. The result is positive if your blood pressure decreases and you feel dizziness or faint during the test. A positive tilt table test indicates (as you probably know) that your heart is beating inappropriately to maintain appropriate blood pressure.

Syncope recurred in 67 (30.0%) subjects. 1). The results of a tilt table test are based on whether you faint during the test and what happens to your blood pressure and heart rate. Second, given the number of positive and negative tests and the number of false-negative and false-positive results in their retrospective study, the reported values of sensitivity or specificity are incorrect. "what do the results have to be on a positive tilt table test? A negative tilt test was ultimately obtained in every patient. 2. Normally your body would enlist a number of mechanisms to prevent fainting...the arteries should constrict, the heart should beat faster to compensate. The median frequency of pretest spells was 0.3/month; after the tilt test, the median frequency dropped approximately 90% to 0.03 per month. There were 146 (65.5%), 39 (17.5%), and 38 (17.0%) type 1 to 3 subjects, respectively. 1. Your blood pressure drops and you faint.
