P波振幅和W值关系的临床观察

THE CLINICAL OBSERVATION ON THE RELATION BETWEEN AMPLITUDE OF P WAVE AND W VALUES

本文采用频谱分析方法，观察了Ｐ波在不同振幅情况下Ｗ值相应的变化。结果表明：Ｗ值在一定范围内随着Ｐ波振幅的增加而增高；但当Ｐ波振幅过高时，Ｗ值反而呈降低趋势。本文提示：在一定范围内，Ｐ波振幅增加，高频成分增多；Ｐ波振幅过高时，由于心肌病变，心房产生的高频成分减少。

The corresponding changes of the W values with different amplitude of Pwave were observed using spectral analysis method.The results domonstrated:W values wereelevated with amplitude increase of p wave,but when amplitude of P wave was tco high,Wvalues had a trend of decrease,It is indicated that high frequency components of atrium in-crease when amplitude of p wave was elevated in definite range。When amplitude of p wavewas tco high,the high frequency components decrease for the pathological changes of my-ocardium.
