I've been working on a ECG signal collected during exercise through my chest mount heart rate monitor. My goal is to accurately detect the location of the R-wave. (For those who are new to ECG signal, R-wave is the narrow peak similar to the ones I circled in red.) Can you guys suggest any method for preprocessing the data so that it will be easier to extract the signal? Like anything! I am just trying to learn new skills right now
I have tried wavelet transform but I am not getting any luck. Come on guys, show me the power of the internet! haha
if you want to try it out, this is the data.
The sampling frequency is 150 Hz.
