How to determine the orders of High pass filter for ECG signal ( cutoff frequency = 0.033 Hz so near 0 Hz) ?

I'm trying to theoretically design a active High-Pass Filter for ECG signal with cutoff frequency Fc = 0.003 Hz...it's too close to 0 Hz and stop band frequency must be greater than 0 Hz . So...
