| 摘 要： | 在心电图（ECG）数据分析中，其QRS综合波检测是关键。本文应用小波变换，首先对ECG信号进行数字滤波，提高信噪比，然后再通过自学习过程确定多个判据来实现QRS综合波的精确检测。经GKD－405A多导智能分析仪实测数据检测，QRS综合波正确检测率达98％以上。

| Abstract: | The key is detection of QRS complex in the analysis of ECG signal. Wavelettransform is used to analyse ECG signal. ECG signal is filted by digital filters, and the QRScomplex can be distinguished from noise, baseline drift, and high P or T waves. Adaptiveamplitude thresholds are employed to make final determination whether the detected event isa QRS complex. This alogrithm has been used in a microcomputer-based medical instru-ment-Intelligent Multichannel Analyser (mode GKD-405A) The QRS detection rate is above98%. |
