双峰T波在儿童心电图中出现率远高于成人.为加深对双峰T波形态和临床意义的认识,我们对部分儿童进行了观察和统计.现将结果报告如下.材料和方法 随机选择587例健康儿童,其中男性352例,女性235例,年龄1个月—14岁,平均6.25岁,均经临床和X线胸片检查证实无心脏疾病.另选有心脏病儿童50例,男性24例,女性26例,其中病毒性心肌炎40例、室间隔缺损10例,年龄2—13岁,平均6.5岁.患儿平卧5—10min后,描记常规9导联心电图. Bimodal T-wave in children with ECG was much higher than in adults .In order to deepen the understanding of bimodal T-wave morphology and clinical significance, we have observed and statistics of some children.The results are reported as follows.Material and method of random selection 587 healthy children, including 352 males and 235 females, aged 1 month -14 years old, average 6.25 years old, were confirmed by clinical and X-ray examination without heart disease.Ordered another 50 cases of heart disease in children, male 24 cases and 26 females, including 40 cases of viral myocarditis, 10 cases of ventricular septal defect, aged 2-13 years, mean 6.5 years old. After the supine 5-10min, the conventional 9-lead electrocardiogram was traced.
