摘　　要：目的:分析直立倾斜试验阳性的患者在达到阳性标准时和晕厥时的血压、心率,探讨阳性标准对直立倾斜试验结果的影响。方法:对727例行直立倾斜试验患者的数据进行分析。结果:患者发生晕厥时的血流动力学明显比达到阳性标准时恶化(P<0.05)。结论:在直立倾斜试验中当患者出现阳性反应时,不应急于终止试验,而是继续观察,直至患者晕厥或出现明显心动过缓或窦性停搏而足以诊断为心脏抑制型,对于大于4 min仍未出现上述反应的患者,也应终止试验。Objective： To investigate the effects of blood pressure（BP） and heart rate（HI/） ot patients with a posmve response to t11t table test when getting to positivity criteria and syncope. Methods： The data of patients with a positive tilt table test were analyzed in 727 pa- tients. Results： The hemodynamics of patients with loss of consciousness were worse than those of getting to positivity criteria （P〈0.05）. Conclusion： When patients get to positivity criteria in tilt table test, doctor should not terminate the test until they lose consciousness or HR drop to a low level which is enough to diagnose the cardio-inhibitory forms. The test should terminate if the time is more than 4 min- utes from getting to positivity criteria and patients do not reach the response above.
