小儿克山病的心向量图分析张晓娴，姜丽晶，纪树彦小儿慢型克山病的心向量图主要表现在反映心肌除极的ＱＲＳ环形态、运行方向及方位的异常，心肌复极异常表现在Ｔ环方位、形态、ＱＲＳ／Ｔ及Ｔ环长／宽比值的改变。我们认为心向量图对克山病的诊断优于心电图。资料和方法... Cardiac vector diagram analysis of pediatric Keshan disease ZHANG Xiaoxian, JIANG Lijing, JI Shuyan The cardiac vector diagram of pediatric chronic Keshan disease is mainly manifested in abnormal QRS ring morphology, running direction and orientation that reflect myocardial depolarization. Myocardial repolarization abnormalities manifest in T Ring orientation, morphology, QRS / T and T ring length / width ratio changes. We think the cardiac vector plot is superior to Keshan’s diagnosis in ECG. Data and methods ...
