BACKGROUND: Head-up tilt test (HUTT) remains a cornerstone in the diagnosis for unexplained syncope since its introduction in 1986. Several factors have been elucidated as possible predictors of a positive tilt test, which include among others, age, sex, and early heart rate rise. Investigations have also been undertaken to observe response to different medications used in the evaluation of syncope during head-up tilt test
OBJECTIVE: It is the objective of this study to determine the profile of patients with suspected neurocardiogenic syncope undergoing head-up tilt test and the factors that may predict a positive test outcome
METHODS AND RESULTS: There were 86 patients included in the study. Majority presented with symptoms of syncope and presyncope. Total case findings rate was 37 percent for all cases, which increased to 74 percent in patients presenting with a classical prodrome. Age, sex, and ECG did not correlate with a (+) HUTT while the presence of prodrome and early heart rate rise correlated significantly with the outcome. The complication rate was 1 percent
CONCLUSIONS: HUTT is a useful tool in suspected neurocardiogenic syncope with 74 percent case finding rate. The presence of classical prodrome and an early heart rate rise may be a useful guide in predicting a positive outcome for the test. (Author)
