you are letting your anxiety get out of control with these worries of hyperthyroidism and atrial fibrillation.
severe anxiety can cause you to have heart palpitations.
your thyroid doses are best determined by your blood tests.
if you have regular blood tests every 4 months, then this will tell what dose you need.
a dose increase of 100-125 will not cause you heart problems.
it sounds like you need to be treated for your anxiety symptoms. your anxiety is getting in the way of your doctors properly treating you and helping you.
