I'm 23years old. Can I have breast implants with a pacemaker?

You are still a candidate for surgery, but I would require medical clearance from your cardiologist prior to moving forward.  The implants should not cause any issues for you when replacing the pacemaker.  Best of luck!

Hello and thank you for your question. This should not be a problem and I have performed breast augmentation in patients with this exact same story before.  You would need to obtain medical clearance from your cardiologist prior to surgery.    This entire surgery can be performed with a
small incision technique.  Make sure you specifically look
at before and after pictures of real patients who have had this surgery
performed by your surgeon and evaluate their results.   The most important aspect is to find a
surgeon you are comfortable with. I recommend that you seek consultation with a
qualified board-certified plastic surgeon who can evaluate you in person.
Best wishes and good luck.

This should not be an issue- as long as the wire won't be stretched out by the implant, etc. Usually, the pacemaker needs to be demagnetized so it is not affected during surgery. Clearance with your cardiologist would be necessary as well as An exam and consultation with a plastic surgeon is recommended to discuss your options and expectations.
