In my experience doctors don't get into suggestions of what to give up unless we present an activity as a trigger. Will you be telling the MD what activities seem to trigger problems with your heart rate?

I like the book "The Afib Cure" by John Day and another cardiologist. Some of it might apply to SVT. They do focus on giving up triggers in order to avoid meds, but of course also write about those who need meds after those efforts.

Acceptance of limitations is tough. I can walk 10 miles in a day but can barely lift a seltzer bottle. I have osteoporosis too with fractures. You are lucky to still be lifting. But a PT may be able to help you find alternatives to help bones.
