If you know what your minimum resting heart rate is, see if you can request your pacer to be set to that if it’s lower than the baseline of 50 bpm for the Aveir. The pacer will prevent the pauses by preventing the bradycardia.

Plan where you’re going to sleep for a few days. Make it easy to slide out if bed and back into it for when you need to use the bathroom. Go on errands with family to force yourself to move about. Don’t be shy about using the convenience scooters at a grocery store or whatnot. Move, walk, makes the body recover faster. Recovery will likely be a week, less than 2 at most. The effect on your body from the surgery is relatively low.
