Athena,
Welcome!
Your heart can be checked very easily for damage — ask your doctor to do the required tests just to make yourself feel better. Everyone is different, everyone’s bodies react differently to the same “onslaught,” so there is plenty of chance that your heart is fine. Just test so you can stop worrying.
If your symptoms have not abated since your RAI, what’s happened to your thyroid levels? Your doctor should be monitoring your levels fairly regularly until you go hypo, since that needs to be corrected with thyroid replacement hormone as soon as it becomes evident.
I guess I’m saying that both of these questions are best answered by your doctor.
GOOD LUCK and better health soon!
