how high does a thyroid reading of the t3 and t4's have to be before u will start getting heart palptiations

Answer 1

Each person has his own individual thyroid function T 3 ,T 4 levels as normal , and people tended to fluctute slightly within their own range.
Serum TSH is typically normal or reduced and may be markedly low, although usually not less than .05 uU/ml .
Lab readings do not correlate with clinical features like palpitation etc.
