一种处理ECG信号中噪声的新方法

A New Method for Lowering Noise of ECG Signal

讨论了用频域叠加平均的方法处理 ECG信号中的噪声。这种方法可以克服以往在时域中无法解决的初始定位问题 ,这就给自动处理噪声带来了可行性。这种方法最后得到的是一个完整且低噪声的 ECG周期 ,其中包含了有用的各种特征信号 。

In this article, a new method is introduced to reduce the noise in ECG signal. We use accumulation division method in frequency area, which can solve the problem of locating the initial position. This problem exists definitely in time area. By using this method, automation in disposing the noise can be realized. The result of this disposing is an integrated and low noise level cycle of ECG signal, which contains all useful characteristic signals. We hope it will be convenient for doctors.
