I would be interested in hearing from anyone who has experienced tachycardia as a side effect of thyroid therapy, especially anyone who has tried more than one therapy (e.g. T4 only, T3/T4 combo, Armour, even different
brand names) and can tell me what worked for them.
Does tachycardia eventually go away once a stable thyroid dose is reached, or is it permanent?
I would also like to hear from people who might have had good results using something other than atenolol for the tachycardia.
