At last, the validation of QRS detection and t wave detection was implemented using the MIT-BIH Arrhythmia Database and the QT Database separately.
最后分别利用了MIT—BIH数据库和QT数据库对QRS波检测效果和T波检测效果进行了验证。
The detection algorithm that adopts tow-level finite difference and extremal theory is used to locate the R wave and the one-level and tow-level derivative methods is used when detect QRS wave.
对于R波,采用二级差分和极值方法定位,对QRS波群采用一阶导数与二阶导数并用算法进行检测。
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。
