【摘要】：目的探讨血管抑制型血管迷走性晕厥(VVS-V)儿童心室晚电位(VLP)变化。方法收集2006年7月至2013年1月在中南大学湘雅二医院儿童晕厥专科门诊就诊,经直立倾斜试验(HUTT)明确诊断的VVS-V儿童184例(研究组)。年龄4~14岁,平均(10.54±2.15)岁。男85例,平均(10.85±2.01)岁;女99例,平均(10.27±2.24)岁。同期按性别及年龄匹配中南大学湘雅二医院儿童保健专科门诊进行健康检查的儿童105例为对照组。采用广东中山博爱医用电子仪器厂的SR-1000A心电综合自动分析仪对受检者进行VLP检测,比较研究组和对照组儿童VLP变化。结果研究组较对照组心率(HR)降低[(83.96±12.27)次/min对(87.28±13.75)次/min,t=-2.113,P0.05]、总QRS时间(TQRS)延长[(84.89±12.05)ms对(81.21±8.23)ms,t=3.070,P0.05]、高频低幅时限(LAS40)延长[(62.43±19.17)ms对(56.79±1.83)ms,t=2.442,P0.05]、均方根值(RMS40)增加[(28.73±7.23)μV对(26.89±7.36)μV,t=2.059,P0.05]。结论 VVS-V儿童较健康儿童HR降低,TQRS、LAS40延长,RMS40增加,提示VVS-V儿童有可能会发生心血管恶性事件。
[Abstract]:Objective to investigate the changes of ventricular late potential (VLP) in children with vasosuppressive vasovagal syncope (VVS-V). Methods 184 VVS-V children (study group) who were diagnosed by vertical tilt test (Hutt) were collected from July 2006 to January 2013 in Xiangya second Hospital of Central South University. The average age was (10.54 卤2.15) years. The mean age of male was (10.85 卤2.01) years, and that of female was (10.27 卤2.24) years old. At the same time, 105 children who were examined by sex and age in the outpatient clinic of Xiangya second Hospital of Central South University were taken as the control group. VLP was detected by SR-1000A ECG automatic analyzer in Zhongshan Boai Medical instrument Factory in Guangdong Province. The changes of VLP in children in study group and control group were compared. 缁撴灉鐮旂┒缁勮緝瀵圭収缁勫績鐜，
