Discrete extremum method of ECG-QRS detecting based on LabVIEW

摘要: 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.

Abstract: 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.
