No: Thyroid profile is normal. Eliminate caffiene & other stimulants in your diet and follow up with your doctor.

No.: You apparently aren't hyperthyroid. You have readings in the normal ranges. You might become hypothyroid in the future because your ft4 is at the low end of normal. It is therefore very unlikely that this is the reason for your svt.

No: These are still in normal range should be repeated in 3-4 m avoid caffeine but if still have svt, it's likely an intrinsic cardiac issue.
