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 includes among others, age, sex, and early heart rate rise. Investigations have also been undertaken to observe response to different medications used in the evualation of syncope during head-up tilt test.
METHODS AND RESULTS: There were 68 patients included in the study. Majority presented with symptoms of syncope and presyncope. Total case findings rate was 37% for all cases, which increased to 74% in patients presenting with a classical prodome. Age, sex and ECG did not correlate with a (+) HUTT while the presence of podrome and early heart rate correlated significantly with the outcome. The complication rate was 1%.
CONCLUSIONS: HUTT is a useful tool in suspected neurocardiogenic syncope with 74% 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.
OBJECTIVE: It is the objective of this study to determine the profile of patients with suspected neurocardiogenic syncope undergoing hea-up tilt test and the factors that may predict a positive test income.
