As an electronics engineer, I can assure you that your defibrillator has a far greater chance of interfering with your detector than the other way around. Because of exposure to all sorts of electronic radiation and signals, your defibrillator is built using a technique known as rad-hardening or radiation hardening. Not the nuclear type of radiation here but the EMF type. EMF stands for ElectroMotive Force, which can be electrical fields, magnetic fields or a combination of both. Even walking around in your house could affect your machine due to the 60hz AC flying about. Want to know how sensitive electronics can be? Go look at a touch-on / touch-off lamp. They work by senseing the 60 HZ signal that your body picks up from your house wiring.
Your pacemaker will be shielded from external emissions but you and your doctor are wise to be sure in the safety of his office. He'll be able to tell right away if there are any issues. Just for a goof, try putting the coil close to your pacemaker and see what happens. Then try putting the control box there. A good friend of mine jammed up his White's DFX machine to the point where we had to do a factory reset on it. He had leaned the control box on his shoulder (near his pacemaker) as he kneeled down for a target. It went completely silent and all functions stopped working. I see that you have the same model.
There was a schoolyard another friend and I loved to hunt that had a neighboring shopping plaza which had an ultrasonic alarm system. Normally quite harmless but his DFX detector was unusable there. He always borrowed my Compadre when we were there.
Be cautious. It'll pay off and it's harmless to check in the doctor's office. Be more cautious about exerting yourself and working up a sweat. Ask your doctor about this but when you exert yourself, your heart rate and breathing go up. This happens even in people who are in terrific shape. When that happens, your body is screaming for oxygen and your heart and lungs provide it. In a few minutes, the need is fulfilled and your heart and breathing return to normal. Now, with your pacemaker, when your brain says "more oxygen," your heart will respond, your lungs will respond but your pacemaker will say, "No, no no!" This can cause you to faint. Fear not, the results are almost never a long lasting problem but if you bang yourself up when falling, you can have ancillary damage to your other parts. Just try not to exert yourself. Take plenty of breaks and even when you don't feel you need it, sip some water.
Metal detecting is a very gentle form of good exercise and you can easily control your exertion levels. What you can't control is a panic reflex from turning over a rock and seeing a snake or that panic you feel as a strange dog runs toward you. Either of those can cause a conflict between your heart rate and your pacemaker. Just be ready for those moments when they happen. Try to hunt with a buddy nearby to keep an eye on each other. I wish you the best with your pacemaker. Your life will be changed for the better.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.
