心电信号的实时滤波和压缩处理对于ECG的分析研究具有很大的意义,文章提出一种基于FPGA来实现对心电信号实时处理的方法,在FPGA内部采用FIR滤波和LADT压缩算法来实现对心电信号的实时处理,从而不但降低了模拟电路的复杂度,而且提高了系统的性能,经仿真实验验证,该系统可以很好的满足性能要求,并且具有系统结构简单紧凑、成本低、调试方便等优点。

ECG real-time filtering and compression is very significant for analysis and study of ECG signals. The paper put forward a method to real-time process ECG signals based on FPGA, which dealt with both ECG signals filtering and ECG data compression in the FPGA. So the system reduced the complexity of analog circuit and improved the performance of the system. With the artificial and experimental verification, the system could meet the performance demands , besides the system had the merits of simple and compact structure, low cost and convenient debugging.
