分析3086例出生至50岁各年龄健康人心电向量图 QRS 环运行方向、最大向量方位、初始5ms向量及终末向量方位。结果表明:QRS 环图形具有显著的年龄特征,在心电向量图诊断上具有重要意义。对由婴儿 QRS 环特点演变为成人向量环图形的过程进行了讨论。
Analysis of 3086 healthy people from birth to 50 years of age Healthy ECG QRS ring running direction, the maximum vector orientation, the initial 5ms vector and the end vector orientation. The results show that: QRS ring graph has significant age characteristics, and is of great significance in the diagnosis of vector diagram of ECG. The process of evolving baby infantile QRS rings into adult vector ring graphics is discussed.
