To explore the change of the amplitude of P wave, T wave and ST segment of 12 lead electrocardiogram (ECG) in children with breath holding spell.
A total of 29 children (24 males and 5 females) with breath holding spell in Second Xiangya Hospital, Central South University were enrolled for this study from October, 2009 to September, 2015. Their ages ranged from 3 months to 6 years, with an average of 1.82±1.27 years old. The control group consisted of 30 age-matched and gender-matched healthy children. All subjects were underwent electrocardiography by the SR-1000A comprehensive automatic electrocardiograph analyzer, and the changes of the ECG parameters were compared between the two groups.
Compared with the control group, the amplitude of P-wave of V5 lead was decreased [(44.10±23.98) vs (58.30±21.19) μV, P<0.05], the amplitude of T-wave of V6 lead was increased [(423.80±122.6) vs (350.00±105.73) μV, P<0.05], the amplitude of ST segment of II lead was increased [(84.80±39.97) vs (57.30±38.77) μV, P<0.05], the amplitude of ST segment of aVR lead was increased [(-77.60±37.41) vs (-51.00±33.46) μV, P<0.05], the amplitude of ST segment of aVL lead was increased [(35.20±28.24) vs (17.70±33.90) μV, P<0.05], the amplitude of ST segment of V5 lead was increased [(111.00±59.36) vs (69.00±36.33) μV, P<0.05], the amplitude of ST segment of V6 lead was increased [(79.30±45.51) vs (51.30±33.19) μV, P<0.05].
The children with breath holding spell have autonomic nerve dysfunction. The amplitude of ST segment changes is sensitive.
探讨屏气发作患儿12导联心电图P波、T波和ST段振幅的变化。
选取2009年10月至2015年9月在中南大学湘雅二医院就诊的29例屏气发作患儿（男24例，女5例），年龄3个月至6岁，平均（1.82±1.27）岁。对照组为30例年龄、性别匹配的健康儿童。所有受试者均采用SR - 1000A综合自动心电图分析仪进行心电图检查，比较两组心电图参数的变化。
与对照组相比，V5导联P波振幅降低[（44.10±23.98）μV vs（58.30±21.19）μV，P<0.05]，V6导联T波振幅升高[（423.80±122.6）μV vs（350.00±105.73）μV，P<0.05]，II导联ST段振幅升高[（84.80±39.97）μV vs（57.30±38.77）μV，P<0.05]，aVR导联ST段振幅升高[（-77.60±37.41）μV vs（-51.00±33.46）μV，P<0.05]，aVL导联ST段振幅升高[（35.20±28.24）μV vs（17.70±33.90）μV，P<0.05]，V5导联ST段振幅升高[（111.00±59.36）μV vs（69.00±36.33）μV，P<0.05]，V6导联ST段振幅升高[（79.30±45.51）μV vs（51.30±33.19）μV，P<0.05]。
屏气发作患儿存在自主神经功能障碍。ST段振幅变化较为敏感。
