I am working on "ECG Signal denoising using Artificial Neural Networks". I need noise free ECG records. ECG records which I have downloaded from Physionet contain baseline wander as noise. Can anyone tell me where to obtain noise free versions of these records ?
Hi Shavika,
i guess it will be difficult to find ECG recordings without any noise (at least if you think of real ECG recordings).
ECG that potentially show less noise are short term recordings because patients typically are at rest. Maybe you could have a look here:
https://www.physionet.org/physiobank/database/ptbdb/
(perhaps even some noise estimate is available which you could use to preselect appropiate records).
Greetings, Sebastian
In such case we may use either the physiological training station like BIOPAC, there are some function built already in MATLAB to generate pure ECG.
It is really easy to get rid of baseline wander. I would just use it as an opportunity to improve your skills. Baseline wandering is related to frequency. Essentially it is a lower frequency drift. Just use some additional filtration. Try a band pass filter to eliminate lower frequency noise.
