摘　　要：目的探讨小儿扩张型心肌病(DCM)与同步12导联心电图P、QRS、T波综合振幅及ST段变化的关系。方法52例DCM患儿(研究组),选择匹配健康儿童52例为对照(对照组)。受检对象用广东中山SR-1000A心电自动分析仪描记同步12导联体表心电图,计算机回放,选择清晰波形自动分析合并人工干预,测量各导联P、QRS、T波振幅及ST段振幅。结果与对照组比较,研究组RavL振幅、RⅠ+SⅢ振幅、RV1+SV5振幅显著增大(P<0.01),RavF振幅增大(P<0.05),总P振幅(∑P振幅)、总QRS振幅(∑QRS振幅)显著增加(P<0.01),总T振幅(∑T振幅)显著降低(P<0.01)。Ⅰ、Ⅱ、aVF、V1、V4、V5、V6导联ST段下移(P<0.05或<0.01),T波振幅除Ⅲ、V3导联增高外其他导联均降低(P<0.01)。结论同步12导联心电图P、QRS、T波综合振幅及ST段变化能客观评价小儿DCM心脏扩大及心肌缺血,具有较好的临床诊断效果。Objective Investigate to 12--lead electrocardiogram （ECG） ,P wave, QRS wave, T wave amplitude and ST segment changes in children with drlated cardiomyopathy（DCM）. Methods 12--lead simultaneous body surface ECG were taken from 52 cases with DCM （research group） and 52 mate healthy children as control（control group）. The P wave, QRS wave, T wave amplitude and ST segment amplitude were tested by artificial during three clear wave cycles of ECG. Results RavL and R t ＋Sin and Rv1 ＋ Sv5 and RavF amplitudes obviously raised and ∑P and ∑QRS amplitudes significantly increased （P 〈0. 01） and ∑T amplitude markedly decreased （P〈0. 01） and ST segment depressed IP〈0. 05 or 〈0. 01）in lead Ⅰ , Ⅱ , aVF,V1 ,V4 ,Vs ,V6 and T wave amplitude reduced in other leads except lead Ⅲ and V3 in research group compare to the control. Conclusions ECG 12--lead P wave, QRS wave, T wave amplitude and ST segment changes can objective evaluate heart enlargement and myocardial ischemia in children with DCM. It shows ECG is of a better clinical diagnosis effect to DCM.
