Main Question or Discussion Point

I have been trying to solve this problem without any success. Not homework, just curious how to solve this, I'm trying to deduce physical models. Honestly I have no idea
how to attack it, so I'd really appreciate if you could please provide some help.

This is electrodynamics applied to medical physics.

Suppose n-dipoles are colocated in the ventricular tissue of the heart with a certain
fixed horizontal depth, which we denote by x.
Assume all these n-dipoles have constant dipolar moment, i.e they are continuously distributed. Now imagine a system of coordinates and suppose the n-dipoles are located at the points (x,y) where x is the fixed horizontal depth and y is the height (vertical distance between the dipoles), y is varying.

How would you write the expression that describes the potential field generated by these n- dipoles? under the assumptions previously mentioned.

I know it's an integral, but don't know how to attack this problem.

Thanks in advance.

at large distances you can just sum up all the dipole moments and treat it as one big dipole, i think.. Maybe you could just calculate the potential of each dipole and then sum up all the individual solutions, choosing an appropiate coordinate system (you could let a computer do this for you).
