ECG, FFT and IFFT

Actually, I am using this source by Phyionet.

el_supremo:
But if you want to do real-time collection, analysis and display of ECGs, the MEGA would not be my first choice :slight_smile:

Oh... really?

Actually, I want to do that!

Can you explain me why and to say me a alternative device/way to do that (any other choice)?
