Objective: To compare the difference of children (under 18 year-old) and adult (over 40 year-old) in head-up tilt test (HUTT) positive patients.
Methods: All patients diagnosed as vasovagal syncope in HUTT from January 2005 to December 2015 in Chung-Ang university hospital. Any patients with underline disease excluded.
Results: The mean age was 13.5 years (from 7 to 17 years) and 59.3 years (from 40 to 85 years) in children and adult respectively in HUTT positive patients. There was no sex differences in children and adult [male: 57 (35.4%) vs 65 (43%) (p =0.167)]. The positive rate of passive test was statistically different in two groups [54 patients (33.5%) vs 23 patients (15.2%) (p <0.001)]. The highest heart rate (HR) and delta HR in Type I positive in passive test was statistically different in two groups [highest HR: 107.8 bpm vs 91.0 bpm (p <0.05); increase delta HR: 35.8 bpm vs 22.5 bpm (p <0.001); decrease delta HR 38.0bpm vs 25.6 bpm (p <0.05)]. The HR values except at baseline in Type I positive in provocation test were statistically different in two group [highest HR: 138.4 bpm vs 113.5 bpm (p <0.001); lowest HR: 88.7 bpm vs 77.3 bpm (p <0.05); increase delta HR: 64.5 bpm vs 44.4 bpm (p <0.001), decrease delta HR: 49.7 bpm vs 36.1 bpm (p <0.001)].
Conclusion: The positive rate of passive test and HR differences in HUTT were statically different in two groups.
