How to process ECG signal ?

Dear Members,

What filter should I use for analyzing ECG on my ADC？ I use AD8232 for getting the input signal.

Thanks

If you haven't already, I would thoughly read the AD8232 data sheet.

AD8232

Eliminating or reducing noise before it is amplified is always preferred to filtering. The data sheet provides several application circuits and filtering suggestions.
