给出了一种基于小波变换的QRS波检测方法,采用MIT-BIH数据库进行验证,准确率达到99.5%。然后,将该方法移植到嵌入式系统上,实现了心电信号的实时检测。该方法具有延迟少,计算量小等优势,有良好的应用前景。

A method based on wavelet transform has been developed for detecting QRS-waves.The MIT-BIH database is used to evaluate this method, and the accuracy is over 99.5%. Then the method is implanted into the embedded system to implement the real-time detection of ECG. This method has good performances in time-delay and computation.
