Results Of the 186 post-exercise syncope patients, 141 had a positive TTT results(75.81%), most of them were male(102/141). Most of the syncope were vasodepressor syncope(106/141).
结果186例运动后晕厥患者有141例在TTT中出现阳性，阳性率75.81%，且以男性（102/141）、血管抑制性晕厥（106/141）患者占大多数；
Methods TTT were undergone in patients with post-exercise syncope and a negative result in exercise testing.
方法活动平板运动试验结果阴性的运动后晕厥患者，均进行TTT。
ConclusionMost of the post-exercise syncope were vasodepressor syncope. TTT is the first choice to distinguish post-exercise syncope with a negative tread-mill exercise testing.
结论运动后晕厥多属血管迷走性，TTT是鉴别活动平板运动试验结果阴性患者运动后晕厥的首选方案。
