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, P<0.05]、总QRS时间(TQRS)延长[(84.89±12.05) ms对(81.21±8.23) ms, t = 3.070, P<0.05]、高频低幅时限(LAS40)延长[(62.43±19.17) ms对(56.79±1.83) ms, t = 2.442, P<0.05] 、均方根值(RMS40)增加[(28.73±7.23) μV对(26.89±7.36) μV, t = 2.059, P<0.05]。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:

Abstracts: Objective To investigate the changes of ventricular late potentials (VLP) in children with vasovagal syncope of vasodepressor response (VVS-V). Methods Totally 184 children [aged from 4 to 14 years old,the average age being (10.54±2.15) years old] had been diagnosed with VVS-V by head-up tilt table test (HUTT) (study group) from July 2006 to January 2013 in the Second Xiangya Hospital of Central South University, male 85 cases, the average age of (10.85±2.01) years old; female 99 cases, mean age (10.27±2.24) years old. Totally 105 healthy children were matched as controls. All subjects underwent VLP examination. Investigate the difference in HR, TQRS, LAS40 and RMS40 between the study group and the control group. Results Compared with the control group, in the study group heart rate (HR) decreased [(83.96±12.27) beats/min vs(87.28±13.75) beats/min, t = -2.113, P<0.05],the total QRS time(TQRS) [(84.89±12.05) ms vs (81.21±8.23) ms, t = 3.070, P<0.05] and high frequency and low amplitude limit(LAS40) [(62.43±19.17) ms vs (56.79±1.83) ms, t = 2.442, P<0.05] were prolonged,and the root mean square plant(RMS40) increased [(28.73±7.23) μV vs (26.89±7.36) μV, t = 2.059, P<0.05]. Conclusions Compared to healthy controls,in VVS-V children HR reduces,TQRS and LAS40 prolong,and RMS40 increases. It suggests that VVS-V childrenare more likely to have cardiovascular incidents.
