Processing of a ECG signal
0
My question is about signal processing. I detect peak from a ECG signal but now I want to remove the peak value from the ECG signal. Actually I want to replace the peak with a lower value. How can I replace it? I am using python and the
peakutils
library for peak detection which was applied in smooth signal. I smoothed the signal using
butterworth
and
signal.lfilter
python signals signal-processing

The code you wrote and data you used would also be helpful

@ Alexandre Nixon...actually i want to train those data for detecting what types of arrhythmia someone have...for that i need to know the another two peaks which are smaller than the main peak..but bigger than the others noise....i used mit data base for different types of arrhythmia detection......some suggestions will really be helpfu...

@Michael C i am using mit ecg data for arrhythmia detection...and i am using python package scipy for signal.butterworth and signal.lfilter for removing noise and smooth the signal...then i used peakutils for detecting higher peak....now i need to to know the lower two peak than that...is there some threshold amplitude module in python which i can use....thank you for your enthusiasm

So what about simply replacing the peak values with some good old python syntax arr[arr > peakThresholdValue] = newLowPeakValue
