基于LabVIEW的心电信号QRS波群离散极值点识别法

Discrete extremum method of ECG-QRS detecting based on LabVIEW

提出的离散极值点识别方法,其特点是在充分应用LabVIEW强大的信号处理能力的基础上,采用只抽取ECG中少数个特征极值点作为分析识别的对象,是一种检测识别QRS波的新方法.用美国麻省理工学院的MIT-BIH心电数据库进行实验分析的结果表明,这一方法具有算法简化、信号处理速度快、识别精度高和检测定位受基线飘移影响小等特点.

By using LabVIEW＇ s powerful ability of signal processing, the discrete extremum dot QRS detecting method is given based on LabVIEW, only using a little extremum dot as source data is enough to analyse ＆ inspect the QRS peak. This is a new method in the domain of ECG＇ s QRS detecting technology. By using the ECG database of MIT-BIH, the result shows that this method make the processing faster and the algorithm simpler, the precision increased, the effect on base line moving decreased.
