Design a Band-Pass Filter
1st order filters are pretty easy as in this case such as yours. Good job.

But if you have a dual Op Amp, why stop at 1st order when you can make a second order High and Low Pass filter by combining two Butterworth Bandpass Filters.

Compute geometric centre of each -3dB breakpoints


\$\sqrt(500^2*1000^2)=707 Hz~~~~~\$  then \$BW = 500 Hz\$ = 1000-500  for -3dB points with -12dB/octave on either side.

Let's choose a Butterworth response




Notice (inserted time response in green)  how each edge of the 100Hz square wave produces a sinus wave resembling the heart QRST wave but in fact is faster than the rep rate of a muscle AXON wave.  This is due to the center/BW ratio . You can change the shape of each hump but this is forward ,backward with +/- edges.
