研究概览
简要总结
In the present study the investigators evaluate the sensitivity and specificity of passive tilt test in athletes, as well as their haemodynamic responses and autonomic nervous system activity during head-up tilt. Moreover, the investigators try to apply a novel algorithm for the improvement of diagnostic yield of tilt test in athletes.
详细描述
We examine athletes with a history of reflex syncope and athletes without history of reflex syncope.All subjects undergo a tilt test, for the evaluation of haemodynamics, heart rate variability (HRV) and baroreflex sensitivity.

结局指标
主要结局
sensitivity and specificity of tilt test in athletes as measured by the occurence of syncope/presyncope during tilt test
时间窗: 30 min
sensitivity = number of subjects with syncope/presyncope during tilt test/ number of subjects with a history of reflex syncope, specificity = number of subjects without syncope/presyncope during tilt test/ number of subjects without history of reflex syncope
次要结局
- Parameters of baroreflex sensitivity during tilt test(30 min)
- Parameters of haemodynamics during tilt test(30 min)
- Parameters of heart rate variability during tilt test(30 min)
