摘　　要：目的探讨β受体功能亢进症儿童卧位与立位同步12导联心电图(12ECG)ST-T波变化。方法分别描记34例该症儿童在卧位及立位时的12ECG,对比分析ST-T波振幅及形态变化。结果由卧位变为立位时,直立T波振幅降低主要见于Ⅰ、V3、V4、V5、V6导联;T波由直立或低平变为倒置主要见于V1、V2导联;倒置的T波振幅增加主要见于Ⅱ、Ⅲ、aVF、V1、V2导联;各导联未见倒置的T波变为直立的现象。结论患儿由卧位变为直立位T波形态和振幅有明显变化,体位试验有助于β受体功能亢进症的诊断。Objective To investigate T wave and ST segment variation in 12 - lead electrocardiogram （ 12 ECG） under supine and erect position in children with beta adrenoceptor hyperfunction syndrome. Methods 12 ECG under supine and erect position were taken from 34 cases in children with beta adrenoceptor hyperfunction syndrome. The amorphous variations of T wave and ST segment were analyzed. Results T wavse descended in lead I ,V3 ,V4 ,V5 ,V6 under erect position compared with supine position, and T wave inversion occurred in lead V1 ,V2 and deepened in lead Ⅱ ,Ⅲ, aVF,V1, V2. ST segment amplitude had no significant change between under supine position and erect position. Conclusion T wave morphology and amplitude varied obviously as patients position change from supine to erect position, which may be helpful in the diagnosis of beta adrenoceptor hyperfunction syndrome.
