| 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. Wavelet transform is used to analyse ECG signal. ECG signal is filted by digital filters，and the QRS complex can be distinguished from noise. baseline drift. and high P or T waves. Adaptive amplitude thresholds are employed to make final determination whether the detected event is a QRS complex. This alogrithm has been used in a microcomputer-based medical instrument-Intelligent Multichannel Analyser(mode GKD-405A) The QRS detection rate is above 98%. |
