Question hi - you have answered a question for me before - i am 43 - blood pressure usually 115/65 to 120/80 max - about 80kg - only meds thyroxine 100mcg - ecgs all normal
i had atrial flutter and pacs whilst on too high a dose of thyroxine - i had 2 episodes of atrial flutter - both very short and self terminating
since my thyroxine dose has been lowered - abt 8 weeks ago all in all - i have not had any more atrial flutter and hardly any pacs - altho i still get the odd day with a few
my question is - how often do pacs trigger atrial flutter in a normal heart?
can i expect to get atrial flutter again - even though my thyroxine overdose appears to have been the cause?
it seems the thyroxine triggered the pacs too - will they ever go now - or is it the case that once a site is triggered - it just remains triggered
thanks for your help

Answer Dear Ms. Harris,
I'm not sure about the PAC's but flutter is much less likely to occur in the normal thyroid state than in hyperthyroidism. I think PAC's are less likely to be triggered when your thyroid state is normal, but PAC's occur in so many normal, healthy, euthyroid people that I'm not sure. How about letting me know over the next year if your PAC's stay away?
