英文摘要:

This study aimed at examining three tilt angle-based positive responses and the time to positive response in a head-up tilt test for children with orthostatic intolerance, and the psychological fear experienced at the three angles during head-up tilt test. A total of 174 children, including 76 boys and 98 girls, aged from 4 to 18 years old (mean 11.3 +/- 2.8 years old), with unexplained syncope, were randomly divided into three groups, to undergo head-up tilt test at the angles of 60 degrees, 70 degrees and 80 degrees, respectively. The diagnostic rates and times were analysed, and Wong-Baker face pain rating scale was used to access the children′s psychological fear. There were no significant differences in diagnostic rates of postural orthostatic tachycardia syndrome and vasovagal syncope at different tilt angles during the head-up tilt test (p > 0.05). There was a significant difference, however, in the psychological fear at different tilt angles utilising the Kruskal-Wallis test (chi(2) = 36.398, p < 0.01). It was mildest at tilt angle 60 degrees utilising the Kolmogorov-Smirnov test (p < 0.01). A positive rank correlation was found between the psychological fear and the degree of tilt angle (r(s) = 0.445, p < 0.01). Positive response appearance time was 15.1 +/- 14.0 minutes at 60 degrees for vasovagal syncope children. There was no significant difference in the time to positive response, at different tilt angles during the head-up tilt test for vasovagal syncope or for postural orthostatic tachycardia syndrome. Hence, it is suggested that a tilt angle of 60 degrees and head-up tilt test time of 45 minutes should be suitable for children with vasovagal syncope.
