qrs wave amplitude qrs波群振幅
Objective To investigate the age trend of the frontal QRS axis in a normal population and its effect on QRS-wave amplitude in the limb leads.
目的调查和评估正常人额面QRS电轴的年龄趋势以及对肢体导联QRS波振幅的影响。
The method USES both frequency property and amplitude property of QRS wave and gets better detection results than the traditional method, which USES frequency property of QRS wave only.
该方法充分利用了QRS波的频率特性和幅度特性，比传统的只利用频率特性的检测方法精度要高。
