Here we summarize the advances in research of VVS in pathogenesis and treatment.

现对VVS的发病机理和诊治方法的研究进展作一综述.

AbstractObjectiveThis study aimed to compare and discuss the economic value of the traditional and new diagnosis approach to VVS in children.

目的对儿童血管迷走性晕厥（VVS）的传统诊断程序与新诊断程序进行卫生经济学评价。

Objective: To evaluate the value of sublingual isosorbide dinitrate ( ISDN) adminstration before tilt table test ( TTT) as a simple practice test for diagnosis of vasovagal syncope ( VVS).

目的：探讨直立倾斜试验（TTT）前舌下含服硝酸异山梨酯（ISDN）对诊断血管迷走性晕厥的价值。

Objective To probe prediction of recurrent syncope in children with vasovagal syncope ( VVS ) through head-up tilt table test ( HUTT ).

目的探讨直立倾斜试验(HUTT ) 对儿童血管迷走性晕厥 ( VVS ) 反复发作的预测价值.

Objective To probe the variation of QT interval dispersion ( QTd) and P-wave dispersion ( Pd) in supine and erect position for children with vasovagal syncope ( VVS).

目的探讨血管迷走性晕厥（VVS）儿童卧、立位QT间期离散度（QTd）及P波离散度（Pd）的变化。方法直立倾斜试验（HUTT）阳性的VVS患儿46例为研究组。

At present, head up tilt test is the gold standard for the diagnosis of VVS.

目前认为直立倾斜试验（HUT）是诊断VVS的金标准。

Conclusion: Tilt test in diagnosing of VVS is safe and effective.

结论倾斜试验诊断血管迷走性晕厥安全有效。

To reduce the possibility of accident and the frequency of reproducible by summarizing the experience of nursing 86 patients with vasovagal syncope ( VVS) when taken head-up tilt table test and treatment.

总结86例血管迷走性晕厥患者在作直立倾斜试验前后以及治疗过程中的护理经验，以减少意外伤害及再次发作的次数。

Vasovagal syncope ( VVS ) is a frequent clinic apsychia syndrome.

血管迷走性晕厥 ( VVS ) 是一种常见的临床晕厥综合征.

There were no differences in QTd and Pd in supine and erect position in different gender with VVS children ( Pa0.05).

VVS患儿在卧位、立位时QTd及Pd不存在男女性别差异（Pa0·05）。
